OpenVPN 3.4 Windows

1

has anybody managed to connect to htb with the recent openvpn connect 3.4 release?
Apparently they made the switch to openssl 3.0. I get certificate verify failed. THM doesn’t work
either. Any ideas?

you can downgrade security in advanced settings that seems to “fix” the issue for now.

It seems that some users are experiencing issues with connecting to Hack The Box (HTB) and TryHackMe (THM) using the recent OpenVPN Connect 3.4 release. The error message suggests a problem with certificate verification, which might be related to the switch to OpenSSL 3.0.
