Seafile Drive - suddenly stopped syncing without any warning

Dear all,

Hope you can help me out with this.
We’ve been using the seafile drive for a few weeks now. A colleague noticed that he didn’t see some files in a library that another colleague had.
After checking the log file there were several errors and it seems that the Seafile drive had stopped working for already a day! So this colleague was still updating files and didn’t even know that Seafile Drive wasn’t syncing anymore…thank god we could recuperate them all from the cache.
He never received a visible error from Seafile drive and everything seemed ok, so he had no clue.

This is the error we saw in the log
