Openvpn Crashes

[lou]

Hi! A few days ago. I restored pfsense 2.0.1 backup. Since then, Openvpn crashes when i try to connect with clients. The server service stops. I remove all certificates and all openvpn servers. I reconfigured again, but the problem persist.

Anyone know how to fix it?  Can i reinstall a openvn?

Thank you!

Not enough detail here to speculate about what's actually wrong…

What does the OpenVPN log contain (Status > System Logs, OpenVPN tab)

Edit the OpenVPN server, make sure you have the right cipher selected, such as AES-128-CBC

Then make sure the client is set to use the same cipher.

Hi! It works, thank you.

What happened? I know that the server and client didn't match. Do you know by why?
