Windows Desktop client synchronization fails on network error after VPN is up

Hello

Having a big Documents folder to scan, it takes minutes to scan local folders
When you start a VPN during this process, the client continues to do a local scan, but when the scan terminates, it tries to reach the server and it fails with a big “network error”
It should be easy to overcome (just try to reconnect on a network error)
It happens to me most of the time, and I did’nt get that problem with the owncloud client before
Hopefully most of our clients are owncloud clients, buit we need something stable in order to migrate to NXC14 or 15 for next summer.
We are on NXC13 but I believe it’s not server related.
