Can't open a website on home pc but can open it on phone and tablet

podgeandrodge

I can't access a website on my home pc (and internet access is fine for all other browsing) but I can open the site on my phone and on an android tablet. I just get a "internet explorer cannot display the page".

I've also tried Google Chrome to no avail. (It says "cannot connect to ..")

How can my phone and tablet access a site my pc can't?


site is:

www.agencedumas.co.uk

Thanks for any advice.

Victor

Does the PC have Flash installed?

podgeandrodge

Hi
Yes, and I just checked via Adobe for the latest version. It's not even getting to try and open any part of the webpage at all. Weird!

thanks.

podgeandrodge

Anyone else - anyone have a problem opening this website?

www.agencedumas.co.uk

It's working on my work pc, my tablet and on my phone, just not on my windows 7 pc....:mad:

Have tried Internet Explorer, Google Chrome and now installed Opera to no avail...

joeKel73

Works fine here. (W7, Chrome)

podgeandrodge

Thanks foto joe.

Update: I've just ran software to change my ip address and was able to visit the site no problem at all.

When I stop the software I can't visit the site again

change your tcp/ip settings to obtain ip address automatically and obtain dns server address automatically

podgeandrodge

hi obplayer

they were the settings already there. Also tried Opendns with no effect.

I can access the website using my phone via the UPC connection so it isin't an ISP issue either...

podgeandrodge

also just tried http://hidemyass.com/ - a web anonymizer and was able to visit the site no problem

This suggests my ip address is the issue

Well you do have a problem, don't you!
I would look at firewall / antivirus settings. If you can access the website on other devices it does suggest the problem is with your PC.

i have this problem reguraly, what i do which works 90% of the time is go to command prompt, type in 'ipconfig/release' and then wait until a long list appears, if it does not repeat on til the list appers, then type into command prompt 'ipconfig/renew' a long list should appear and hopefully your internet works just as good again

ShatterProof

You probably clicked on a link/program that changed how you connect to internet.
As obplayer said set ip and dns to auto (dhcp) and make sure proxy is not set

Tea_Bag

try doing a winsock reset. always fixes any internet problems i have.

Fix Winsock Manually on Windows 7

1. Open up the command line utility (click start -> type "cmd" -> right click and 'run as administrator' and enter:

netsh winsock reset catalog (resets winsock entries)
netsh int ip reset reset.log hit (resets TCP/IP stack)

2. Reboot your PC

old_aussie

Do you have Malwarebytes Pro installed?

podgeandrodge

@Jameshurst - thanks but no joy.

@shatterproof - thanks but ip and dns are at auto and no proxies.

@teabag - done but no luck thanks

@old_aussie - no, but I've ran free malwarebytes and no problems have come up and also ran spybot with no joy.

Thanks for all suggestions. At this stage it's not about needing to get to the website but a challenge to figure out how one website cannot be visited except from behind an ip hider of some sort...so far tried hidemyass and facehide and was able to get through to the website.

Could someone with UPC confirm they can visit the site please (foto joe I'm not sure who you were with when you tried). Internet is working perfectly in all other respects - speed, all websites visited etc etc..

bonzodog2

Site opens fine here with Opera via UPC

podgeandrodge

shutdown my firewall to no avail...only hiding the IP does it..

dilallio

Have you checked your hosts file to see if something has hard-mapped an invalid IP address to that URL.

The hosts file is generally in the C:\windows\system32\drivers\ directory.
Open it with Notepad and see if there is an entry containing that URL. If there is, comment it out with a # symbol at the beginning of the line.

It's unlikely to be this, but worth a shot.

podgeandrodge

hi dillallio

No luck I'm afraid - had tried that after browsing a few hundred forums yesterday - only one sample hosts file there..

thanks for your suggestion though.

the website IP address begins with 193....this would not be getting the computer confused at that range would it (in the sense of local addreses beginning with 192....)

podgeandrodge

I disabled my UPC connection and started Joikuspot on my phone to set up a new wireless signal.

Connected to this hotspot with my pc and was able to access the website no problem at all.

So it is not the pc.

So this means it must be

1) UPC or
2) that website does not like my normal IP address?

fionny

try:

Click Start / Run / Cmd press enter.

type ipconfig /release press enter
type ipconfig /flushdns press enter
type ipconfig /renew press enter

clear browser cache and history and try again.

Alread tried most of that from below but tried again anyway..

But my ip address has to be part of the problem given that I can access any other wifi connection and go to the site or hide my ip and get to the site.

Razzuh

It's very unlikely your UPC ip is the problem. When you say you can access the site using your phone or tablet, are those using your wifi (UPC connection, I assume you have wifi) or using mobile (3G) internet?

I have UPC and no problem connecting by the way. Their ip beginning 193 would not cause a problem, that's not an issue.

I'd say the problem is either:

1)There is a UPC problem routing to the server where the site is hosted (it's in france by the way). Unlikely since other UPC people have no problem.

2)It's a DNS issue (most likely) Were you able to get the ip from your home pc?

Do this: Click start and type 'cmd' in the search box (or click 'run' and then type 'cmd' if you're using windows XP).

At the prompt, type 'tracert www.agencedumas.co.uk'

I have attached a screenshot of what my results look like. Take a screenshot of your results if you can and reply (or just copy and paste). Then we'll see how far you get and we'll have a better idea where the problem lies.

podgeandrodge

Hi Razzuh

Visit site on my phone with 3g connection – OK
Visit site at any other PC elsewhere – OK
Visit site on my phone using my UPC connection via wifi – OK
Visit site on my PC using UPC connection either wired or via wifi – FAIL

I am able to get my IP address via “whats my ip” – 46.7.xxx.xx

Tracert below



Thanks for all your suggestions.

If you can get the site using your wifi then your IP or your router couldn't be the problem. Any devices using your UPC connection are all sharing the same public IP address.

The problem does seem baffling. I would guess though that it's something to do with the PC, since everything else seems to be doing its job. Both issues 1) and 2) above I mentioned seem now to be ruled out since the trace route worked fine. I can't really think of anything else right now that hasn't already been effectively ruled out.

Try this anyway:

Go back to command prompt on your PC ('cmd').

Type: 'telnet www.agencedumas.co.uk 80'

The window should change to just a flashing cursor at the top.

Type: 'HEAD / HTTP/1.1'
hit the Enter/Return key once.
Type: 'Host: www.agencedumas.co.uk'
hit the Enter/Return key twice.

I'll warn you that you probably will not be able to see what you're typing for the above, you'll just see the cursor move along. Type carefully and it's case sensitive.

Then you should see something like I get in the image attached. Please post back with whatever you get. Also, repeat the instructions above but instead of the word HEAD type GET this time. If this works you'll get a whole pile of text that you don't need to bother taking a screenshot of. Just check through it and see if there's a big blob of something that looks like english in the middle (the same text that's on their homepage). If it doesn't work though and you get a short response, post a screenshot of that back here.

There might be something in the responses that's useful.

Hi Razzuh

enabled telnet on windows 7 but not connecting



tried without port 80 and it still failed (on port 23)

Razzuh

Since you can't connect that way either at least it pretty much rules out your browser. It's port 80 we care about because that's the port that web servers listen on. Port 23 would only be for a telent server and we wouldn't expect them to be running one of those.

It's possible your IP is been blocked, but that would definitely have blocked your phone too. Are you sure 3G was disabled on your phone when you viewed the page using wifi? It could have fallen back to using 3G otherwise when the connection via wifi failed.

These sites are hosted at the same IP as agencedumas.co.uk:

www.agencemercure.fr

www.ab-immobilier.fr

www.grimal.fr

www.espritdazur.com

Give them a click in your browser and see if you can view them. I'm guessing you can't. You may as well also try the french version of the site you want to visit:

www.agencedumas.fr


Also, would you go back to telnet once more and try this instead:

telnet 193.228.156.39 80

Same thing basically but bypassing the dns lookup.

None of those sites load for me on UPC, tried Google DNS, same thing, must be a routing issue on UPCs side

Nick

Mr. Presentable

All work for me on UPC

Thanks for that Nick. Really helps. So it seems a lot of people on UPC, including myself, are able to connect fine but others can't. I wonder are you and the OP in the same geographical area? Maybe that has nothing to do with it.

If it's a routing problem though it doesn't make any sense that other devices using the same connection can connect while one PC can't. Are you sure your mobile devices weren't using mobile data (3g) podge? It would have to be disabled to be sure you're suing wifi.

Absolutely. I've used my Archos tablet which doesn't have a 3g connection at all just wifi and it works no problem using my UPC wifi. Weird eh

Thanks.

I'm in Terenure/Rathgar.

Great to know it might not be my PC

Do you have any other hardware that you could try using the UPC connection? To see if, like me, you can access the sites via UPC but not on your pc? Thanks.

Razzuh

Well if it doesn't have 3g then we know it's using wifi. And you don't have anything on there that is making you use a proxy server (something like a hide-my-ip thing again)? VPN software would also have the same effect. It all basically means that you're not connecting directly to the server, you're using a middle man, which solves your problem.

To me, if your tablet can connect using the same connection without any of the above, that says
a) it can't be a routing issue
b) it can't be your IP, since it will be using the same public IP as the PC
c) it's unlikely to be your router

That means it has to be something to do with your PC. Probably something in your network settings (unlikely since all other browsing is fine), or else a setting in your firewall or antivirus that's blocking the incoming or outgoing connections to the server IP.

It could also be any kind of filtering software like the kind that filters to protect kids getting at certain sites. Do you have anything like that?

It's also possible that there's something you've installed that's interfering with your connection to this server in particular. This would be very weird though and I can't really think of anything that would. If this is the case, it would probably be something like file-sharing software (torrents, peer2peer). Maybe voice over IP software like Skype. If this is the case, it might be something both yourself and Nick have installed.

The best way I can think of to test this would be to restart windows in safe-mode with networking.

Directions:
http://windows.microsoft.com/en-US/windows7/Start-your-computer-in-safe-mode

In advanced startup options, choose safe-mode with networking.

Once it boots up, open your browser and see if you can get to the site.

Then restart normally and let us know. Don't keep browsing in safe mode because it's not secure without anti-virus, firewall etc.

Let us know how it goes.

Im in the Ranelagh area, interesting would be close by to you op... Still those sites not loading, just timing out page cant be displayed

Nick

podgeandrodge

The tablet is deffo running off my UPC with same IP address.

I have no filtering software and just running stock zonealarm/avg antivirus/super antispirware.

Nick - did you try other hardware to connect to the website? Thanks.

Started in safemode with no joy.

Interesting that Nick is in Ranelagh and I am in Terenure...

yoyo

Still not loading for me:
Grimal.fr-UPC connection-Times out
Grimal.fr-Three 3G connection on phone-Loads slowly but works

UPC seem to have some routing issues, strange its only affecting some customers though...

Nick

Edit: Maybe not a UPC problem, Grimal.fr works on my phone over Wifi on my phone :O

podgeandrodge

so it doesn't seem to be UPC given that the UPC wifi is working for both of us on other hardware...

And I can't see how it is the PC given that I can visit the site on my pic by using another internet connection.

That means it has to be UPC related

yoyo

I tried manually setting an IP (rather than DHCP) and still the site doesn't load, real strange one this, out of interest are you using the Thomson modem?

Nick

podgeandrodge

yep, using the thomson.

try hidemyass and see if that works for you like it did for me.

yoyo

Interesting what modem are you guys using who can access those sites, I wonder is it that the thomson cant display the site over ethernet but allows it over wifi, weird but possible :S

Nick

Edit: Problem Solved: The issue is with the Thomson modems firewall, turn that off and the sites load fine, although I reccomend you don't leave it off. Something to make UPC aware of though

Fair play to you Nick! What made you even think of that!

So the modem firewall doesn't apply to wifi connections made over it then?

yoyo

podgeandrodge wrote: »

I'm guessing the firewall has more rules over a wired network than wireless, so it could be whatever is blocking the site in the firewall is only affecting wired connections. Working it out was really a case of trial and error, narrowed it down to a firewall issue, I wouldn't leave off the modem firewall though, but bring it to UPCs attention

Nick

podgeandrodge

Informed UPC who hadn't heard anything like this before. They will look into it and come back to me in a couple of days.

Thanks to everyone who offered the suggestions, I know I've learnt a little more than I knew before!

podgeandrodge

No response from UPC despite promises to ring back in 2 days.

Keep at them, in fairness it probably Thomson who maintain the firmware not UPC but they should be able request Thomson to fix it!
