EDIT: It was a firewall issue. I disabled my firewall and it works.

https://listmonk.app/

The site loads properly on serverIP:5870 and if I change proxy_pass http://127.0.0.1:5870; to proxy_pass http://listmonk.mydomain.com:5870; then it will load on listmonk.mydomain.com:5870. But it gives the 502 error when I visit the site without the port.

If I set proxy_pass http://127.0.0.1:5870; and visit listmonk.mydomain.com:5870 I get:

The connection for this site is not secure
listmonk.mydomain.com sent an invalid response.

    Not the docker container IP. The IP of the machine you are running docker itself on. Nginx is running in a container, it’s not allowed to talk to the other docker container IP directly and it has a separate network stack from the listmonk container, so 127.0.0.1 only goes back to nginx.

    Say your machine that you are running docker on is 192.168.0.67, the listmonk docker container is 172.16.0.89, and nginx container has an IP of 172.16.0.34.

    Your nginx config would need the proxy to point to 192.168.0.67:5870.

    Then make sure you don’t have ufw or some similar firewall blocking the connection from nginx to listmonk.
