The output of your Apache/nginx/system log in /var/log/____:

No logs present in that location on my Docker install

Output errors in nextcloud.log in /var/www/ or as admin user in top right menu, filtering for errors. Use a pastebin service if necessary.

See pastebin link above

Because of your Pastebin i think you have set SMB/CIFS. But i think you need Local.
Also make sure that the user rights (user:group www-data:www-data) are set correctly.

I was trying SMB/CIFS, but only after attempting to link local external storage. I did see that the local attempts didn’t seem to be registering on the log.

The actual solution was much simpler. I was trying to link the absolute path, but this is a Docker install so I obviously had to mount the drive in the docker-compose first, then link the symbolic path :man_facepalming:
