Long Certificate Renegotiation Times

Post by chockomonkey » Mon Jan 21, 2019 8:31 pm

I'm looking for a place to start troubleshooting this issue I have.

I'm using the latest Access Server with local authentication. Connections are made over UDP, although I am running in dual daemon mode (both UDP and TCP), and have enabled auto-logon.

I've also tested authentication with the authcli script which succeeds instantaneously. The initial client vpn connection also happens within seconds.

The problem arises during renegotiation only, where it takes upwards of 2 minutes to renegotiate and re-authenticate the new key.

I have considered just increasing the time before renegotiation, but I figured I'd start by asking if this long delay is typical, and if not, where I can start troubleshooting why it takes so long.

Thanks all!

Only during TLS key refresh, right? On OpenVPN 2.4.6? Then it's a known bug. Will be fixed in a next released.
