openvpn3 @3.8.3: Main thread exception: OpenSSL: error:1E08003C:DECODER routines::OSSL_DECODER lib

[zeddit (Dai Zhang)]

I am using openvpn3 client for a while to connect with my openvpn access server. After upgrading to 3.8.3 it tells me the error of Main thread exception: OpenSSL: error:1E08003C:DECODER routines::OSSL_DECODER lib after input a challenge response code of two factor authentication. which makes me could not connect to the server. I have changed the client to use a UI-based openvpn-connect, it could connect with the server, so the server side should have no problem.

I don't know if it is an error of openvpn3 client or it's a problem with the underlying openssl lib, on my mac, I have installed a version of 3.2.0 openssl3 with macports. I am not sure if there is a standalone version of openssl inside the openvpn3 client.

Seems like the update to openssl3 @3.2.0 has caused problems for many ports.

Can you please provide:

• your macOS or OS X version.
• the full error message (there should be a file name and line number after this), or any other information that would help debug this. The OSSL_DECODER library has many places where it can throw an error, this alone isn't enough to debug this.
• if possible, a copy of your OpenVPN server and client configuration (without the secrets of course), so I can replicate this.

New variant openssl1 added to link against the old openssl as a workaround. Alternatvely use mbedtls variant to use another crypto library.
