Hmmm… can't reach this page error message for certain sites

spupazza

I have a Vodafone mobile broadband, with a Huawei B818 router (provided by Vodafone).

After nearly 2 years, I changed the the SIM to save money and from the one provided by Vodafone with the mobile broadband (which to my understanding is a data-only sim) and bought a normal SIM (the one that can be used on a mobile phone).

Everything is ok, similar speed, no issue except on certain sites, like Reddit.com I get the error message:

'Hmmm… can't reach this page'

Thus I can't reach this site. For Reddit and all the sites I can't reach, I noticed those sites are flagged as not secure.

'The connection to this server is not secure'

Apparently 'the site does not have a certificate'.

Does anybody have a clue on what could resolve this issue?

The issue is not specific to the OS settings (it occurs on Windows, Linux and Android) and different browsers.

Strangely enough on a few occasions, I was able to reach Reddit ,even though I hadn't changed anything.

try flushdns, change DNS on your computer NIC

Thanks for the suggestion, I tried to change the DNS (I tried first Cloudflare and then Google) and flush the dns but didn't seem to have any effect

Vodafone force the use of their own DNS servers with hard wired DNS traffic sent to them. Whatever you put in the DNS field of your router is ignored. If you have an old router this might not be the case but it's still likely they will have pushed a firmware update with this feature.

Seen this happening on my phone with Reddit recently. Might be a new thing with them.

Do you have any parental controls or content filters enabled?

This.

Vodafone mobile SIMs have content filtering enabled by default.

If it's a billpay SIM you can call them up and have it removed, if its prepay you need to go into a shop with photo ID to have it removed there.

Thank you all. It was exactly as you said.

I wouldn't have never guessed since I wasn't aware at all of those filters.
