I have my home server apps configured with NGINX proxy manager and DuckDNS to access remotely, but about three weeks ago DuckDNS URLs stopped working on my home network. I can access 192.168.XXX.XXX:1234 on the home network but myapp.duckdns.org times out.

It DOES work as expected using a VPN or on mobile data.

Any ideas as to what’s going on?

EDIT: I kind-of sort-of got a workaround working using pi-hole “local DNS” feature to point the duckdns URL to NGINX. Didn’t work

EDIT 2: Disabling the router’s firewall completely seems to have fixed it. Still trying to figure out the exact setting that did it. I will update this post if I can.

    Hm, pinging works and shows my (external) IP. But no device I’ve tested can load the duckdns URL.

    EDIT: Two of the URLS show the local IP replying when pinged. Not configured any differently so I’m not sure what’s going on there. This was a PiHole thing apparently
