Unable to connect to Remote Desktop Gateway

Description

I am having a problem connecting to our servers behind a Remote Desktop Gateway. I get the following error when attempting to connect to either of two RD Gateways:

50331656
Your computer can't connect to the Remote Desktop Gateway server. Contact your network administrator for assistance.

The logs on the RD Gateways do not even show a connection attempt. So, it seems as if the client is not even getting to the RD Gateway.

On the same client workstation, I can use Windows native RDP client to connect with no issues.

The RD Gateway FQDN does have a dash in the name, which may or may not be critical here.

Here is the log from the MRemoteNG.log file, showing the connection error:
