Hey guys, Changed ISP to Aussie Broadband yesterday, and suddenly can’t seem to connect to my server using my domain (still can connect in the local network). Aussie Broadband uses CGNAT, and I opted out of that, but I still can’t seem to use the server… am I missing some router settings I might need to change? Any other ideas?

Server firewall is off, ports 443 and 80 are forwarded to the servers nginx proxy manager etc. Using ddns that ASUS provides with their routers and Cloudflare domain

Thanks for any help!

    Too be fair to your ISP, the only thing you should be using 80 for is redirecting to 443.

      Right, but if I can’t redirect (ISP just drops packets afaict) and you don’t explicitly type https:// or use an https link, and I don’t have something like HSTS preload configured for that domain, your browser will just hang if it’s on my system. You can’t just type “lemmy.stuart.fun” and have it work unless you happen to hit my hairpin, i.e. be on my network.

      Mostly I try to keep things I want publicly available on .dev and it just works thanks to the full .dev HSTS preload. But it’s still annoying.
