The issue you are facing:
Hello guys,
I have some issue with my Nextcloud, it’s working fine before but after some problem on my server, i have restarted and this issue occur.
What happened is i cant really download my files from NC, the files are available in the storage, permission is fine, no config changes afaik.
I have restarted my machine, and re-mount the data disk. But its not fixing the issue.
Anyone facing this issue before, or can help with pointing to the right direction for my troubleshooting?
Thanks
