I will add that after this error, even though you press “1” to re-login, syncing seems to just stop. I have a backlog of files on my linux systems and though status says “syncing”, nothing is moving up to the cloud.
me@myserver:/InsyncRoot/HomeSeer$ insync-headless status
Accounts:
me@me.org (Google Drive)
Sync status: ERROR
(See insync-headless error list or insync-headless conflict list for details.)

…but nothing happens. I have tried stopping the service and restarting it, but still once this happens the only way I have gotten it to start syncing again is to uninstall, delete local files and start over.
