If you get error 14187180 like I did after trying the above answer https://askubuntu.com/questions/1233186/ubuntu-20-04-how-to-set-lower-ssl-security-level (or otherwise) you might like to try the --dtls-ciphers=LEGACY with openconnect. I needed to both downgrade to TLSv1.1 as above (MinProtocol = TLSv1.1) and add this to connect to a customer's Cisco Anyconnect VPN.

echo password | OPENSSL_CONF=/etc/ssl/openssl_tls_1_0.cnf openconnect -v -g VPNGROUP -u username --dtls-ciphers=LEGACY --passwd-on-stdin vpn.domain
