The issue you are facing:
The logs /var/snap/nextcloud/current/logs/php_errors.log shows the error:
[23-Jan-2024 22:19:32 UTC] {"reqId":"xxx","level":3,"time":"2024-01-23T22:19:32+00:00","remoteAddr":"192.168.x.y","user":"--","app":"PHP","method":"GET","url":"/index.php/login","**message":"fopen(/media/nextcloud/data/nextcloud.log): Failed to open stream: Permission denied at /snap/nextcloud/39212/htdocs/lib/private/Log/File.php#84**","userAgent":"Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/120.0.0.0 Safari/537.36","version":"27.1.4.1","data":{"app":"PHP"}}
however the file /media/nextcloud/data/nextcloud.log is present and written regularly:
{"reqId":"xxx","level":0,"time":"2024-01-27T22:40:07+00:00","remoteAddr":"","user":"--","app":"cron","method":"","url":"--","message":"CLI cron call has selected job with ID 15226","userAgent":"--","version":"27.1.4.1","data":{"app":"cron"}}
Is this the first time you’ve seen this error? (Y/N): yes, I never had to check error logs before (for other reasons) so I never noticed.
Steps to replicate it:
I’m not sure, but the snap runs as root and /media/nextcloud is a ZFS dataset owned by root:
drwxrws--- 11 root root 17 Jan 27 22:31 data
# ls -l /media/
drwxr-xr-x 3 root root 3 Aug 29 2019 nextcloud
The snap otherwise works, I can upload and browse files.
