Windows 10 2004 remoteapp keeps wanting to use 3389 not 443 with 2016 RDweb , worked fine on 1909

Question

Hi

We are running a 2016 rds stack and have rdsweb using port 443 for no problem for last 18 months.

users on windows 10 1909 had no issues opening the rdweb icons, and accessing the published app over port 443.

however once windows 10 is upgraded to windows 10 2004, when you attempt to open a published app, it attempts to communicate over port 3389 and not 443 (captured via packet capture)

only way around we have found is to install the remote desktop app from the windows store, which seems to make the connection work fine and uses port 443, however we cannot ask all our customers to install this app, when everything was working fine with their 1909 PCs

we have made no changes to the 2016 RDS stack and can easily replicate the issue between windows PC upgraded to 2004 and not upgraded.

Anyone else encountered this issue?
