Hey guys. I’ve just set my things up (using nginx reverse proxy) and it worked great till today morning, when everything came crashing down, aka all my domains aren’t working anymore for some reason, even though I was just using it yesterday night. I basically haven’t done anything besides starting it up. the containers work, they can be reached via my ip+port. (vaultwarden, navidrome, nextcloud and portainer). the reverse proxy can’t be wrong, since it worked till yesterday just fine, so I have no idea anymore. ( my SSL certificates are made with certbot)
Has your public IP-Address maybe changed? Verify its the same as in the DNS records (curl ifconfig.me).
Are you trying to access the external domain from inside your network or from outside (i.e. phone or something) ?
