Using latest version, both at the server and client. I will check later what specific version on both sides, but they are using >2.4.2 for sure.

    Which OpenVPN version is this? If you're not running v2.4.0 or newer,
    try upgrading. I believe this this have improved there, cf.
    https://github.com/OpenVPN/openvpn/blob/release/2.4/Changes.rst:
    
    [...]
    
      Dualstack round-robin DNS client connect
        Instead of only using the first address of each --remote OpenVPN
        will now try all addresses (IPv6 and IPv4) of a --remote entry.
    
    [...]
    
      * proto udp and proto tcp now use both IPv4 and IPv6. The new options
        proto udp4 and proto tcp4 use IPv4 only.
