Openvpn works with another provider and I found that for the provider that does not work adding the following to the openvpn config file will correct the situation. It should not be needed they should be able to provide the needed cipher.
# Permit legacy CBC cipher the server pushes
data-ciphers AES-256-GCM:AES-128-GCM:CHACHA20-POLY1305:AES-128-CBC
# Fallback for servers that don't negotiate data-ciphers
data-ciphers-fallback AES-128-CBC
# Permit legacy CBC cipher the server pushes
data-ciphers AES-256-GCM:AES-128-GCM:CHACHA20-POLY1305:AES-128-CBC
# Fallback for servers that don't negotiate data-ciphers
data-ciphers-fallback AES-128-CBC
