I’m using, W10 Pro.
I suspected that my ISP could have blocked it for an unknown reason, but i’m unable to contact them at these hours so I decided that I would make sure that issue was not on my end first.
Desktop PC > [EthernetCable] > Router > ISP
Unfortunatly the ISP doesn’t allow edits to some of the settings, and insists that I should be paying a tech to visit just to change the DNS.
I presume that router is under your ISP’s control then, right?
From your traceroute it would seem as if the connection is already stopped at your router (if we rule out the possibility of your computer being involved). What model is your router?
The Internet does not seem to have too much on that model in regard to Cloudflare’s DNS service, but https://wuseman.github.io/SAGEMCOM-FAST-5370e-TELIA/ does seem to refer 1.1.1.1 in context with that router, so it might actually be a reserved address on that model. I cant confirm that however. It might be best to clarify this with your ISP.
I’ve got Sagemcom [email protected] 5370 Air / Telia Zone Hybrid router on Telia FI and it has the same issue. It uses 1.1.1.1 internally for something, Telia FI confirmed this but did not say anything about a fix.
