MAC sync: invalid JSON value



my MAC Sync App is not working since few days and I got the following error:

Status: syincing
error while connecting to remote server (invalid JSON value received while getting remote changes)

I did all the possible test, changing directory, re-installing the app but nothing happened.
I have MacOS High Sierra
Thanks a lot


could you tell me which Pydio version you’re using, sync version and on which system is your server ?
