I'm running zabbix 3.4.14 on Arch Linux and I'm seeing TLS authentication issues after upgrading openssl from 1.1.0.i-1 to 1.1.1-1 (the `-1` part is the Arch Linux package version). Downgrading openssl to 1.1.0.i-1 resolves the issue so I'm inclined to believe that this is a backwards incompatible API change in openssl, possibly due to TLS 1.3 support described here: https://wiki.openssl.org/index.php/TLS1.3#PSKs

The agent is configured to accept incoming connections from the server and also actively connect to the server. Both parts fail if the agent is using the the new openssl version.

I have also opened this same issue on the openssl tracker here: https://github.com/openssl/openssl/issues/7241

Below is a part of the log generated by zabbix-agent with the OLD openssl version, filtered with `grep -i -C8 -e tls -e psk`
