Hello,
I have installed mailcow on my vps server. Among other things run more docker with the port 443. I have also adjusted in the mailcow.conf the line:
HTTP_PORT=8080
HTTP_BIND=127.0.0.1
HTTPS_PORT=8443
HTTPS_BIND=127.0.0.1
SKIP_LETS_ENCRYPT=y
Also I installed Nginx Proxy Manager to be able to assign the ports correctly, unfortunately I always get a 502 error through my domain now.
Can anyone help me further?
