OpenVPN failed to create tunnel after failover after upgrade to 25.1.7

[ajr]

I upgraded may backup node and then did a failover to (persistent CARP switch) to upgrade the old master.
The OpenVPN client could not create a tunnel.
I switched back to the master with old master and the tunnel came up.

Does the OpenVPN configuration needs a change with 25.1.7, related to:
openvpn: add port-share as advanced feature
openvpn: add (push) block-ipv6 option
