In the fall I noticed my lets encrypt (SWAG) docker wasn't able to renew certificates.
Since then I have checked with my ISP and they are not blocking port 80 or 443.
My router logs show port forwarding from internet location to my server. I have external port 80 forwarded to my server port 180 and likewise external 443 to server 1443. My router logs specify the external IP:port and LAN server IP:port - so I can confirm messages are getting to my router. I have plex set up for port forwarding as well and it works just fine externally so I assume the router port forwarding is working.
Inside my Unraid server I have tried changing swag docker ports and my port forwarding from the router. I have cleared and reinstalled the docker container and have tried both version of nginx proxy manager as well. They all give me a cannot communicate on port 80 error from Let's Encypt. I have confirmed the containers all can ping the internet.
When I try to open the web interfaces locally for NextCloud container it gives me a cannot connect error, but bitwarden container does open.
I noticed on my SWAG docker network the container address for port 80 keeps changing to match my server port (eg 180).
I am at a loss on how to diagnose this point, any suggestions would be appreciated.
