Hello,

I have update my Pydio Server to new version (8.0.1 enterprise) but I have a issue when I want synchronize my local folder on my Mac to my Pydio Server.

I copy multiple folders and files to my local folder, the PydioSync work correctly. But when copy a specific file, PydioSync stop working and I this error : Token-based authentication failed, reload credentials?  
If delete this png file and reconnect PydioSync, the synchronization it’s ok.

Do you have a solution about my issue ?

For your information, my troubleshooting :

- Upload another png files : OK
- Change the name of my png file : NOK
- Compress my png file to zip : OK
- Upload another big file : OK
- Change folder of png file : NOK
- Upload my png file with Pydio UI Server : OK but PydioSync it’s NOK
- Clean Install : NOK
- Clean Install on another Mac : NOK
- Create new Workspace : NOK

Bellow pydio.log of Pydio Sync :

hi,  
some basic questions :

- what was your previous version of pydio ?
- Did you check the various troubleshooting in the Admin Guide (see Documentation section), especially “Checking Sync & Checking API” ?

I’m having the same issue. There are actually no files yet in Pydio (on any workspace). It is a fresh install, latest version of Pydio and new install of Pydio Sync on Mac OS Catalina.

Once a sync is created in the Mac App and I “fire the rocket” - the result is this Error while connecting to remote server (Token-based authentication failed, reload credentials?)
