openVPN V2 works but V3 errors "peer certificate verification failure"

Post by DonnyRob » Mon Sep 13, 2021 4:57 am

I recently setup an openVPN server and clients in a pfSense box. Every time I try to connect via openvpn 3.3.1 it errors with "peer certificate verification failure" during one of my many bouts of troubleshooting I tried V2.7.1 and the VPN connects and works perfectly fine. Anyone have an idea of what would cause this?

You're not the only one who is having this issue.

There appears to be some backend differences between v2 and v3 that are not entirely obvious. If you've got access to the server and client logs as well as the certificates you should probably reach out to support. https://openvpn.net/support
