Siemens TIA v17 on Win10 BSOD using Openvpn

Post by Bepske » Mon Jul 26, 2021 1:40 pm

Hello forum,
Help please, can someone help or suggest me with a PC that crash every time I connect to a (Open) VPN.

At our company we have been using Open VPN connections very regularly for many years without any problem.

But recently when I (as an Open VPN Client) make an Open VPN connection on my fairly new Windows 10 Pro, this connection is made, but the PC crashes after a few seconds as soon as I want to send something through the connection.
The typical blue BSOD screen of Windows gives no error, only the message Kmode Execption Not Handled, ndis.sys.

There is nothing wrong with the Open VPN connections and configurations, on another PC with Windows 7 it still works fine.

Crashing after a VPN connection also happens with other VPN clients such as Forticlient or others.
I'm pretty sure it's not because of the VPN Clients software, but because of Windows 10 updates.
I’ve made a lot of tests found on internet but nothing helps.

This is very inconvenient for us, I cleaned everything up a bit, reinstalled the last version but nothing helps.

Does someone have an idee
Thanks in advanced.

Thanks TinCantech.

i do not realy understand what you ask with log file --verb 4

And I forget to write that it is good working in Windows Safe mode but not in normal mode.
And is this the right forum, my OpenVpn Gui is v2.5.3 and not "Connect"
Thanks

Moved to the correct board.

Please start here for an example:
viewtopic.php?f=30&t=22603#p68963

The more detail you can provide the better .. but your client log at --verb 4 is a good start.

In advance of that, you may find disabling what-ever security product you use on the client will help.

Thanks for your advice.

Here the log file (sorry, for some security raisons WAN IP etc., I changed some domain and IP keys).

Like I write;
-in Windows Save mode there is no problem at all. Only by normal booting.
-The connexion is working, but after the establishing of the connexion and by the first ping to VPN Server, the PC crash.
-Before it was working but since 2 weeks ago nothing any more.
-It happens with all the Clients.
-I tried with Forticlient, and it is the same problem.
-I also as test disable all the security functions.


Here some content from the log:

Can you check that the drivers and bios for your system and network card are up to date ?

I'm having difficulty understanding the root problem.

Thanks for your comments. I don't understand the root problem also. It's really annoying and puts a lot of work on hold for us.

The BIOS and the network cards are up to date and have the very latest versions.
No Firewall or security programmes cause the problem.

I have uninstalled and reinstalled everything several times. VPN connection is still OK but then a ping to the VPN server crash the PC
In Windows Save mode no problem, everything is OK.
