Can you provide a screenshot or exact error message? I don’t see that anywhere in the code.

Also some context about what you were doing that triggers the error would be helpful if you’d like anyone to troubleshoot your situation.

Just a shot in the dark… Have you checked if the time and date on your server and client computer are set correctly / identically…

If that’s not what causes the issue, I would remove the account completely from the client, rename the synchronasiation folder or backup it up to an external drive and then delete it on the computer. After that log on into the client again and perform a new synchronization.

Make sure you log out from your account before you move or delete the folder on your computer!

If the files in error are present on the server side, check their modification time.
I guess you’ll see ‘1970-01-01’.

I already got this issue, I solved it running the following commands:

  • use find to list all files in error :
    find /path/to/nextckloud/data -type f -newermt "1900-01-01" ! -newermt "1980-01-01" -exec ls -l {} \;

  • If the result seems OK, use ‘touch’ to update modification time:

find /path/to/nextckloud/data -type f -newermt "1900-01-01" ! -newermt "1980-01-01" -exec touch {} +

Then, scan your nextcloud files to update nextcloud database:

sudo -u apache php /var/www/html/nextcloud/occ files:scan

Hope it can help
