Azure Virtual Desktop Login Error Code 0x3000047

Question

Hi

We have been facing issues with logon to Azure Virtual Desktop Windows machine for couple of users in Personal Hostpool.
Users get error when logging on using RDP Client app or the Web Client.

Error Code 0x3000047 and screenshot attached.

Other users in same hostpool can connect without any issues.
We have a hybrid AD architecture and both On-Prem and AAD are in Sync.

Any help on this would be highly appreciated.
It has been a nightmare users machines breaking during production hours with no detailed information/logs on portal.

Thanks
Kanishka

Answer 1

We get that exact error from time to time for hours on end, during which we can't connect for more than 2 seconds until the connection is dropped. And this is on two different AVD sessions in two different regions. Restarts and deallocations of the VM's don't help.

Then, miraculously, hours later or the next morning, everything is fine again for 2-3 weeks. Until it all goes to pieces again, and we have another 2-8 hours of connectivity issues. I think this can also be caused by performance issues on Microsoft's end.

We have three users from three different US time zones having the same issue at the same time each time this happens. Then all of a sudden, we can all get on again.

Firstly, apologies for the delay in responding here and any inconvenience this issue may have caused.

Based on the error screenshot, the reason is "ConnectionFailedAdTrustedRelationshipFailure". This could mostly be issue with UPN being synced to Azure or because of user system domain issue.

Below are similar issue which has troubleshooting steps and hints on resolving the issue.
