Hi Michael,
I have to bother you again with another question. I am using Virtualhere on 10 Raspberry Pis. Seven are RasPis 2B+ and the other three are RasPis 3 B 1.2. All are connected fine over a VPN to a windows machine. All are on auto-use, to enable a scheduled task on the windows machine to download data once an hour. That works absolutely fine for the Raspberry Pi 2. But all three Raspberry Pi 3 are losing the "auto-use" option after a while, and therefore no data is downloaded.
Do you have an idea what could cause this and how I might be able to fix that?
Thanks,
BallerNacken
The Auto-Use will be turned
The Auto-Use will be turned off if there is an error using the device. This is to prevent an infinite loop.
Take a look in the syslog of the raspberrypi 3's and see what the error says. It might be "BIND ERROR" or error resetting.. or something similar.
My guess is the vpn connection drops, the device is stopped being used server side, the connection comes back up and the client requests to use the device because of its "Auto-Use..." setting and that causes an error on the pi3 server side and hence the client turns that setting off.
You might be right here. Just
You might be right here. Just found that in dmesg:

It looks like the onboard WiFi is losing connection due to packets not coming in in the correct order and that comfuses the wifi driver. I will switch to a WiFi dongle and see if that fixes the issue.
