Server missing from Update Manager after activating Azure benefits

It is a bug. Use this link to work around the issue until Microsoft gets it fixed.

https://aka.ms/AUMSAFix

This link will open the Azure Portal with the parameter "Microsoft_Azure_Automation=umflight1" in the URL. Browse to Azure Update Manager in this tab and refresh to see all your machines.

This is not the problem, the problem is the query MS is using to show the Update Manager dashboard.
Try this:

If you go to the machines dashboard in Update Manager, then click open query you get a large predefined query that might show some machines. This is probably the same query Update manager GUI is using.

On line 35 there should be something like:

|where isnull(productFeatures) or productFeatures.name =~ "Hotpatch"

If you add this to the line the servers now added to Azure Benefits should show up in the query

 or productFeatures.name =~ "WindowsServerAzureArcMgmt"

so full code:

|where isnull(productFeatures) or productFeatures.name =~ "Hotpatch" or productFeatures.name =~ "WindowsServerAzureArcMgmt"

The query now shows every server.

Hi @RaymondKristiansen

Welcome to the Microsoft Q&A Platform! Thank you for asking your question here.

I recommend checking that the Azure Arc agent on your servers is up to date. You can do this by running the command 

azcmagent -v.

If it's outdated, updating the agent could resolve the issue. Also, ensure your servers are properly registered in Azure Arc by using this command to confirm everything is connected. 

 azcmagent

If the issue persists after updating the agent, try removing the servers from Update Manager and re-adding them after reactivating the Azure benefits license. You could also try onboarding the servers to Azure Arc first without activating the license, then activating it afterward to see if the servers still disappear. It’s also worth checking the logs in both Azure Arc and Update Manager for any errors that might explain what’s going wrong. 

Note: if you're still facing the issue. please provide the screenshots so that I can guide you.

We are having the same problem, but I am not able to save the query so that it appears correct in the Portal. I suppose that is to be considered a bug to be fixed by Microsoft?
