RemoteApp and Desktop Connections update problem 0x8007052e

Question

I'm experiencing this same problem described here:

Doesn't appear there was ever a posted solution. This seems to impact all users. If you hit update now and manually enter credentials, the update seems to work normally. When the GPO to populate the default feed is first applied, it works as expected. At some point future updates break and won't function again until credentials are entered. We're running Windows Server 2019 and Windows 10.

Answer 1

I think I managed to figure this out. One thing I didn't mention in the description is that we have two different RDweb servers behind a load balancer. This issue seemed to come up whenever we would failover to the second web server. Turned out to be related to an ASP.NET MachineKey nuance setting in IIS. Both IIS instances for RDWeb, Feed, FeedLogin, and Pages need to be the same.
