We are using OpenVPN successfully for a couple of years. Also within Windows 10 without any problems and very stable.
Now, we have updated some Windows 10 computers to the newest version of windows (redstone, anniversary update 1607).
After the update each of the computers has connection problems while connected via OpenVPN client to the OpenVPN server. Every few minutes the network connection is interrupted (RD no longer goes, network shares are no longer available, etc.). OpenVPN doesn’t log any error – even with “verb 5”. The VPN-tunnel will be established all the time.
After 30 to 60 seconds, the connection is restored, until after a few minutes the next cancellation will happen. This “game” is repeated infinitely.
For test purposes I have updated a well working Windows 10 laptop to the newest Windows Version.
Before: everything went well
After: the above mentioned problems happen
The Windows update has changed anything that causing the error.
In addition, I read that in the future Windows will accept only kernel driver signed by Microsoft - but drivers installed before the update will be transferred to the updated system. What shall I do, when I have to install a new OpenVPN TAP-Device within the new Windows 10?
In any case I will be happy to get a solution for my connection problems. Because as it is now it's impossible to work from outside with my mobile device.
Thank you very much in advance!
