Recently we implemented both Duo Auth for RDWeb and RD Gateway successfully. One thing we have noticed is that users that connect to the desktop via Remote Resources (the RDWeb aspx link) on the official Android/Apple Remote Desktop apps can no longer connect. The app is stating that the Web Feed URL is now not valid despite it working prior to the Duo Auth being installed.
As a temporary fix, I have discovered that logging into RDWeb via phone browser and opening the RDP file via the app seems to work as a one time instance but the moment I try to re-launch it stops working.
Has anyone experienced this or knows which of the two applications is likely to be causing it?
