Problem in 2.2.1

[falumas]

Since 2.2.1 my OpenVPN doesn't work well.

The tunnel colapses quite often and I can't get it up and running again.

This is what the client says. It connects fine but after a minut nothing works any longer.

The server also changes the status where the Common Name changes to UNDEF.

Am I doing something stupid here or is it a bug?
