Installed mailcow and it is working nicely. However, as I would like to use apache for my web sites, installed apache and tried configure the reverse proxy for nginx of mailcow. I followed the instructions on https://mailcow.github.io/mailcow-dockerized-docs/firststeps-rp to only get a page with “we are on our way. 502 Please do not stop the stack, while we are initializing the database or do other preparations”.
Probably, I am doing something wrong, but what?
I would appreciate any help. Thanks.
