FSLogix hangs when logging off w/ Blob Storage

Dave Stephenson 56

We've noticed an issue with our AVDs where FSLogix is set to use blob storage/cloud cache.

When logging off, the session will hang on the Please wait for the FSLogix Apps Services message.

There's a known issue that's supposed to fix it, but it's still happening regardless of the FSLogix version we've tested.

We found THIS blog post that talks about some work arounds, but they didn't work for us either.

Has anyone seen this or know how we can get cloud only AVD users?

Hello @Dave Stephenson

Welcome to the Q&A,

To provide a more comprehensive solution to the issue you are experiencing with FSLogix in your AVD environment, I would need some additional information. Here are some details that would be helpful:

What version of Windows and FSLogix are you using in your AVD environment?

What cloud storage solution are you using for FSLogix? Is it Azure Blob Storage, Azure Files, or another cloud storage provider?

Are you using any third-party tools or software in your AVD environment that may be interacting with FSLogix?

Can you provide more details on the steps you have already taken to troubleshoot the issue, including any error messages or warnings you may have encountered?

Have you tried reproducing the issue in a test environment or with a new user profile to rule out any issues with the existing user profiles?

Are there any other symptoms or issues that you are experiencing in your AVD environment that may be related to this FSLogix issue?

I know its a lot, but with this additional information, I can provide a more targeted and effective solution to help you resolve the issue.

Thanks for the quick reply, @Ayomide Oluwaga
I'll try to provide the answers and as much detail as I can. 🙂

The Host is provisioned using the Windows 11 22H2 Enterprise multi-session + Microsoft 365 Apps (Gen2) from the Azure Image Gallery. For FSLogix, we've tested the latest (2.9.8440.42104) as well as an older version (2.9.7838.44263) that was suggested in THIS article and had the same issue with both versions.

We're using a container in a Azure Storage account so we can utilized Azure AD authentication with FSlogix. (i.e. CCDLocations: type=azure,connectionString="StorageAccountAccessKeyConnectionString")

We're not using any 3rd party tools. We went with the generic Microsoft provided image to help minimize the issues/complications.

Initially, our issue was Passwords not being saved when AVD Hosts were rebooted. We worked with Microsoft Support and identified that when logging-in with a FSLogix Blob storage account, we need to add THIS registry key. With that key, the credentials are saved.

Yes. We have tested this in multiple tenants, regions, and with multiple accounts (hybrid and cloud only) and have the same problem with all of our testing.

As mentioned above, we found this issue in testing the issue where credentials aren't saved in AVD sessions when using blob storage accounts for FSlogix. As you may know, this is the only currently supported way to allow cloud-only users to use AVDs.

Please let me know if I can provide any additional details.

Spent about an hour checking on this, seems like a very common problem on blogs.

I'd also like to confirm that you have tried the following:

Increasing the timeout value for the FSLogix Apps service. You can do this by modifying the "HKLM\SYSTEM\CurrentControlSet\Services\frxsvc\WaitTimeout" registry key to a higher value.

Disabling the FSLogix Apps service during logoff. You can do this by creating a script that stops the service before logging off, and then starts it again when the user logs in.

Disabling the "Delete local profile on logoff" group policy setting.

Disabling the "Delete cached copies of roaming profiles" group policy setting.

Let me know how this goes in conjunction with my answer.

Accepted answer

Hello @Dave Stephenson

Glad to help, I did a little research based on the information you have provided. It seems like you have already tried a few different things to troubleshoot the issue. Here are a few more things you can try that might help mitigate the issue:

Verify that the FSLogix service is functioning properly. On the AVD host, launch Task Manager, select the Services tab, and search for the "FSLogix Applications" service. If the service isn't running, try manually starting it.

Make that the Azure Storage FSLogix profile container's permissions are configured properly. Verify that the user accounts that will be accessing the profile container have the required read- and write-access rights.

To see if the problem still exists, try utilizing an alternative storage option for FSLogix, like Azure Files. This can assist you in figuring out whether the problem is unique to using FSLogix and Azure Blob Storage.

Check if there are any firewall rules or network configurations that may be interfering with the connection to the FSLogix profile container.

If the issue persists, consider opening a support ticket with Microsoft to get further assistance with troubleshooting the issue.

I hope these suggestions help you resolve the issue you are experiencing with FSLogix in your AVD environment and I will be glad to help you further.

Thanks!
When I was going through your great troubleshooting steps I found we had inadvertently configured the CCDLocations to go to two storage accounts in two different regions. (Oops!)
When we set it to go to one storage account (in the same region as the AVD Host), the logout time went back to normal.
Luckily, we don't have a need to have the storage profile cached in multiple regions. However, if someone does they may run into the same issue.
