What issue do you have?

I have 2 PC's (both Windows 11), 1 SMB fileserver
PC 1 synchronizes ok
PC 2 does not, sync starts and finishes in a blink of an eye
Both are set to FileSystem, both have exaclty the same url (filepath, \\pc\share\directory)
Both can add, delete and change files in the target directory (outside Joplin)
I use the portable version of Joplin

I don't know what to check next, nor can I find logfiles

Thanks for your help in advance

Herman

Expand the sync status and share the details shown there after syncing. Or ideally send over the full log file

In the profile\log.txt I found some interesting lines

Can I upload the entire file somewhere?

I found the file %appdata%\Joplin\Session Sorage\Log which contained

The 000003.log file is binary and looking into it all I can recognize is "Version.1"

I think the error you posted is the only relevant thing you will get out of the log.

That likely seems like something permission related, but not within the network drive itself, but Joplin being unable to access the network drive.

Check the firewall rules set for Joplin app, or maybe try installing Joplin and see if it's an issue only with the portable app.

I solved it without installing. Just by placing the data on another server.

Thanks for helping me.
