Open VPN Server Crashing UNDEF error



  • Ever since upgrading to the 2.3.x version of pfsense I've had issues with my open vpn randomly crashing. The daemon seems to be running but no clients can connect. Below is what the logs show, any ideas how to resolve this? pfsense's web GUI is also almost always hung and needs restarting (option 16 from pfsense CLI) before I can then restart open vpn. The logs seem to indicate some sort of TLS error, I  have "Enable authentication of TLS packets." checked in the VPN setup, should I remove this? Thoughts on how to resolve this error?
