With one of the last updates the access to control panel was broken.
When trying to access it I’ll get 500 error code “Internal Error The server encountered an internal error and was unable to complete your request. Either the server is overloaded or there is an error in the application.”
nginx-error.log contains this message: "*2144 “/home/user-data/www/default/admin/index.html” is not found " as well as “2256 open() “/home/user-data/www/default/.env” failed”.
I tried to reinstall Mail in a box twice. Didn’t change anything. Can I restore those files without complete reinstalling and restoring MiaB? I don’t know how long access does not work and so I can not rely on a consistent backup.
From the mailinabox install directory, run: sudo tools/web_update
And restart nginx
The file /home/user-data/www/default/admin/index.html should not be there. In fact, the box should not try to serve it to you if you access the admin page. Are you sure you’re using box.<domain>/admin to access the admin page?
Access to roundcube and nextcloud works like a charm.
I found those messages:

I think the best way is to restore the git repository that is your mailinabox installation directory. It is strange that these files are missing, and there might be other files missing as well.
What is the output of git status when run from the installation directory?
Then do a git status again. There should be no more deleted files.
Then check the control panel again, (perhaps another sudo systemctl restart mailinabox is needed)
After resetting and re-checking out everything worked.
Thank you very much for helping me solving this issue.
I checked the logs of my AV. There were no deletions recently.
What I found and I have to investigate is that these files
were identified by git status:
management/testdisk.log
wget-log
This is a VM in a datacenter where I have no access to run testdisk and ftp is not allowed
