But when I try to access the wordpress instance over the browser, to start the installation process. And only got an 502 bad gateway.
The interesting thing is that it already worked before, the only thing what I've changed was, that I am moved all config files and directories, which was before in a seperate folder, to the datadata folder (./data/webproxy) and cut out the services from the old docker compose file to an existing one and also edited file paths from the mapped volumes. Hopefully this are enough details to help me, otherwise let me know when you need more information.
So far,
Daniel
