openvpn breaks with Ubuntu 21 LTS after an update

you need to add:

<code>
tls-cipher "DEFAULT:@SECLEVEL=0"
remote-cert-tls server
</code>
to your config.vpn

The log line of the daemon looks like that:\\


<code>
2022-04-25 08:19:22 OpenSSL: error:0A00018E:SSL routines::ca md too weak
</code>
It is a downgrade of the security and should only be used for Corpex connections!
