Debian openvpn client TLS handshake failed

connecting to XG210_WP03_SFOS 17.1.3 MR-3 or 17.1.2 SSL VPN from Debian 10 Testing (Buster) openvpn client has worked until sometime over the past week when it would no longer connect.  The result is the same with TCP or UDP set on the XG + client or after redownloading the ovpn configuration file from the XG.  The Sophos branded SSL VPN client on Windows continues to work fine.  The Debian system is fully updated regularly so I'm assuming recent updates introduced a compatibility issue.  Anyone else ran into this or have suggestions?
