Comment on UK's O2 network is blocking duckdns.org domains

T-mobile was doing this in the US but only blocking certain ports when talking to my home server, might try putting it on a non-standard port as well and see if you can access the service then.

Oh I know some ports are ok. My SSH and WireGuard get through. Port 80 is redirected to a block page place holder and 443 is interfered with so SSL fails.

Wouldn’t you be on CGNAT though? How are they blocking it - at the DNS level? Have you tried a CNAME record that points your own domain to the actual duckdns domain? Just curious how/why they might be doing this.

I’ve been doing some investigating. It’s not just DNS. Termux doesn’t use the system DNS, it uses Google. But there is still a interference with SSL on 443 and a different page on port 80.
