Desktop client s works with new pool, but web client does not

[WookieGTB]

So this is an odd one.

I've just deployed three VMs into a new pool and configured them. Everything shows as being fine that I can tell. The issue I have is as follows:

If I connect via the WVD desktop client, I can see the pool and connect with no issues at all. 

If i go to the RD Web client, I can see the pool but when I click on it there is no response. Other host pools work correctly. 

Has anyone else come across this?

A lot of trial and error but I fixed it. Something musthave gone wrong during the AppGroup provisioning. I deleted the AppGroup, re-created it and re-assigned users. Now it is working in both web client and desktop client.
