VPN client connects only one time then needs to reinstall

ShadowHunter

Hello,

I'm struggling for days now. I hope someone can push me in the right direction.

I'm trying to run OpenVPN client on Windows Server 2012R2 to an existing, external VPN-server.

The first time I connect all works as normal, traffic goes through the tunnel. However after disconnecting and reconnecting it fails (not sure if where it fails, it looks like authentication succeeds) > It requires a re-install of OpenVPN client and it will again work one time.

I do not have this problem (on the same network with), on for example a standard Windows 10 PC.

I'm not really experienced with OpenVPN. How should I proceed troubleshooting this issue? I'm at my wits' end :-(

Thank you.

S.
