HAProxy + Remote Desktop Gateway

[Mister.Deeds]

Hello together

I am trying to put a Remote Desktop Gateway behind a HAproxy. Background is, I have one domain with one IP address but two remote desktop environments. The address of the first gateway is rdg.example.com and the second is rdg.vdi.example.com. Directly enabled (via NAT port TCP 443 and UDP 3391) the RDP connection works without problems.

Now I have created a HAproxy setting. This is as follows:

I have also created the NAT forwarding for UDP

and the firewall rules

On the remote gateway server I have adjusted the UDP port.

as well as a valid certificate deposited

It seems to find the Remote Desktop Gateway,

but after entering the password the following message appears

I have already tried according to this post https://forum.opnsense.org/index.php?PHPSESSID=rtue2j51iviglar7ugte756698&topic=18429.msg83772#msg83772 to deny http request with "remoteDesktopGateway" but without success.

does anyone have any ideas?

Thank you very much and best regards
