Thanks for opening your first issue here! Be sure to follow the relevant issue templates, or risk having this issue marked as invalid.

Your app key is most likely invalid. You've also made up volume mounts that don't exist and used ports that nothing is listening on in a way that suggests you may have used ChatGPT to generate your compose project.

Hi,

1. key is generated on my server with "openssl rand -base64 32" and tried even "docker run -it --rm --entrypoint /bin/bash lscr.io/linuxserver/bookstack:latest appkey" and copied to the compose.
2. have tried port 80 and 8080 to outside and 6875 inside, and removed volume mounts
   Always an unknown error
   Maybe you know the solution?

[hasansevenler]

For some unknown reason, I always removed the “base64” at the beginning of the key, but now it works :)
