Hi. I also encountered this problem with the SOGo login (master branch at 36b5cccd186090d726de62b6b00d1e842e67aacd
).
I run the dockerized setup and caddy as a reverse proxy and updated the mailcow config accordingly.
HTTP_BIND=127.0.0.1
HTTP_PORT=8080
HTTPS_BIND=127.0.0.1
HTTPS_PORT=8443
When I try to log in to SOGo it redirects to the localhost and the internal TCP port
http://127.0.0.1:20000/SOGo/so/[mail-user]/Mail
I tried to add a port mapping to the SOGo container 127.0.0.1:20000:20000
and route incoming traffic directly from caddy to the SOGO container, without success.
Kind regards
