Hi Daniel,
I actually went so far and did set up a new virtual VM from scratch yesterday evening to test this. I remember I was online last week without experiencing any issues. Lately (friday night) I installed KB4517211 (
https://support.microsoft.com/en-us/help/4517211/windows-10-update-kb4517211), the latest commulative update from Microsoft.
I did not test the VPN right away, but yesterday I tried several times connecting to different servers without any luck.
If you check the link provided here, under Highlights, you'll see the following:
Updates an issue that may cause you to disconnect from a virtual private network (VPN) on cellular networks
Addresses an issue with intermittent virtual private network (VPN) disconnections on cellular networks.
I wonder if it may be any relationship between this and the issue we are experiencin?
I'll try to do a reset but I'm not sure it will help due I'm using a brand new VM...
