I have been using insync on my debian/12.2/bookworm system for a while now, and am basically happy with it. It keeps both a google drive, and a onedrive synced as I specified, and I have gained confidence that it works as expected, and syncs when changes occur on either side.
What I am interested in now is using a vpn with insync running. I am presently using a protonvpn subscription (not free) and the insync is behaving differently, and I am not sure if it is working correctly. It seems when the vpn is active, the insync blinks regularly as if it is on/off continuously and not just on all the time.
What is the general expectations of insync with a vpn running. Do you need to start insync before or after you start the vpn?
