I'm trying to use Joplin inside a LXC container on Proxmox Virtual Environment 6.3-4 . I'm building it on portainer with the docker-compose file from github (joplin/docker-compose.server.yml at dev · laurent22/joplin · GitHub). Not sure how I can check the version for this? Couldn't find anything in the Docker container itself. I tried running this on my local windows PC which works fine. But I can't get it to work in my LXC.
I get this (broken) login page when I go to the IP https://i.imgur.com/x9Upss5.png
When I then login I am referred to localhost:22300 and the page can't be reached https://i.imgur.com/Yy3gpmt.png
I tried entering the IP adress as APP_BASE_URL but that shows the same login page and doesn't let me login either.
