Azure Virtual Desktop Web Client - Hostpools visible but not responding to being clicked on

Hi,

Bit of a strange one this, we have 3 different hostpools configured in AVD and these have been working fine for nearly 3 years now, we originally started with WVD so not new to this.

In the last couple of days we have noticed that although all the hostpools are visible in the web client two of them do not respond to being clicked on. The hosts in those pools are available, and normally any messages related to problems with the hosts would come later after the next authentication prompt.

I have reproduced the issue on Edge, Chrome and Firefox and on both corporate and personal devices. We have not changed any configuration in the time since it was last known to work.

I have tried the 'Windows App' and that works fine to access all three pools which to me suggests the issue is not with the parts of the environment we can control.

Is anyone else having a similar issue?

Regards,

Martyn

    Hi Martyn,

    Thank you for your detailed report. Based on your description, it appears the issue is isolated to the AVD web client and not the underlying hostpool configuration, especially since the Windows App continues to access all three pools successfully.

    This behavior has recently been observed by other users and may be related to a backend change in the web client or session broker service. While no configuration changes were made on your end, we recommend the following steps:

    1. Clear browser cache and test in an incognito/private window.
    2. Confirm that the affected hostpools are assigned to the correct workspace and that user permissions remain intact.
    3. Check the Azure portal for any service health advisories related to AVD.
    4. If the issue persists, consider opening a support ticket with session logs from the affected pools.

    If this guidance helps clarify the situation, feel free to mark this answer as accepted so others can benefit too.

    Thank you so much!!!

    Best regards,

    Thanks, its good to know we are not alone! I have tried clearing caches, cookies and turning off browser protection settings. The assignments / permissions are unchanged, and of course when not assigned the hostpools dont show in the web client as expected. There was nothing on the Azure status or service health pages yesterday I will have another look this morning.

    Regards,

    Martyn

    Hi Burgess, Martyn,

    Thanks for the update, and I completely understand how reassuring it is to know you're not the only one seeing this behavior. You've done a thorough job checking browser settings, assignments, and Azure service health—those are exactly the right steps.

    Since the Windows App continues to work as expected, this still points to a web client-specific issue. We recommend keeping an eye on the Azure Service Health dashboard for any new advisories, as backend changes may not always be immediately reflected.

    If the issue persists and no advisories appear, capturing session logs and opening a support ticket would be the best next step for deeper investigation.

    If my answer is useful for you, please feel free to hit ACCEPT THE ANSWER to support me!!!

    Thank you so much!!

    I am having the exact same problem and it works via the browser for 2 AVD host pools but not for one - The Windows App works fine for all 3 host pools. 2 users so far effected. Tried different browsers, cleared cache no change.

    Just come off a call with Microsoft support, apparently there is an issue the backend team are working on but they could not provide any timescale for a resolution. I also asked when the Azure status / service health would be updated to reflect the fact there is an issue and stop leaving users and admins in the dark, that too is apparently being looked at.

    The only workaround is to use the Windows App until such time as they fix the issue with the web client.

    Regards,

    Martyn
