OpenVPN Stopped work after reboot server

yvisek

Hello!

I had configured and working VPN on server and client. Everythink was working great to time, when was problem with power 230V and server was turned off. Now OpenVPN stopped working. Can you help me?

Console shows (when trying to connect):

You are strongly advised to upgrade your windows client:
https://openvpn.net/index.php/open-source/downloads.html

And then use the Openvpn-GUI not a console window:
https://community.openvpn.net/openvpn/wiki/OpenVPN-GUI-New

It restarts connection all the time. Can you give me hint? :-)

@TinCanTech
Thanks for a tip :-)

Right now, I will put only informations about server, because it do not starts. Client case is future case, and I guess it will work, if server will work fine :-)
