I'm trying to use the RD Gateway to connect to an end user computer. While I can connect to our RD Session Host without any problems, I'm facing issues when trying to connect externally to the end user's machine, receiving a generic error message. I've verified that I can connect from the RD Session Host to the client computer using RDP, which suggests that the firewall isn't the problem. The unique aspect here is that the RD Session Host and the end user's computer are on different subnets, and they use different login credentials since we have two domains in the same building. Any advice on how to resolve this?

Have you tried connecting from the RD Gateway server to the client computer via RDP? That could help verify if the network setup is functioning correctly. Also, check the Resource Authorization Policy on the gateway to ensure the client computer is included as an allowed resource. Remember, you shouldn't connect through the session host; instead, you go through the gateway directly to the client PC.
Did you set up the policies correctly on the RD Gateway server? If you're unsure about which policy, there might be a few to review in your RD setup that could affect external connections.
What kind of error are you seeing exactly? Is port 443 on the RD Gateway exposed to the internet, or is it behind a load balancer or reverse proxy? Also, are your SSL certificates self-signed or from a trusted Certificate Authority? Knowing this could help troubleshoot further.
