OS is Server 2008 R2. In an effort to make the internal and external hostnames match (the SSL cert only matches the public hostname), I edited the bindings for our 'RDWeb' site. This somehow broke WelbyApp and I can't seem to undo it. The error I get is:
Your computer can't connect to the remote computer because the Remote Desktop Gateway server is temporarily unavailable.
I have downloaded the .RDP file from RemoteApp and opened it with Notepad++: the RD Gateway is correct. Worth noting that the RD Gateway does still work to RDP into the TS server via RDC 'connect from anywhere.' Any ideas here? Thank you.
