My nextcloud has been a little wonky after the 29 upgrade. I can get a load screen to login but then get an internal error message on the site. I ssh’d in and ran occ setupchecks and came up with this message
Data directory protected: Could not check that the data directory is protected. Please check manually that your server does not allow access to the data directory.
To allow this check to run you have to make sure that your webserver can connect to itself. Therefor it must be able to resolve and connect to at least one its trusted_domains or the overwrite.cli.url.
Actually this message is not related to the login issue, I have the same message and I am trying to find the solution still, but it does not prevent me from anything.
Also nothing is in the logs.
Can you show the actual login error you get (send to support if it has any private info)?
Not sure what happened… however it seems to let me log in successfully. I did rerun the chown on my data directory last night, but even after that it did not work, but randomly decided to try today from work and it now works.
