Consistent Thin Client Disconnection from WVD Pool

Hello we have been experiencing some random but consistent disconnects from our WVD Pool. We have roughly 10 users and have been getting different event viewer logs for when they disconnect. We have ...

Sbarnet: Thank you for sharing the logs. Unfortunately there isn't enough information to debug the disconnects. I recommend to open a support case and provide activity IDs for the connections you see issues with.

Hi Marco,

We are experiencing the same issue, sometimes users disconnect randomly during the day, others can work without any issue. It looks like an issue with one or a couple of RD Gateway servers serving multiple customers in West-EU WVD infrastructure . I cannot find any information however in the logs of the WVD hosts themselves.

Has anyone had luck with Microsoft Support going through this issue?

Thanks in advance

Best regards,

Marco Brouwer

Hi, thanks for the response! I really wonder if we experience the problems at the same time.

Our experience:

- Friday March 6th: No problems

- Monday 9th: Over 75 disconnects (16 concurrent users)

- Yesterday: No problems

- Today: No problems (yet).

Can you run this:

Import-Module -Name AzureAD
Import-Module -Name Microsoft.RDInfra.RDPowerShell
Add-RdsAccount -DeploymentUrl https://rdbroker.wvd.microsoft.com

Get-RdsDiagnosticActivities -TenantName <<TENANTNAME>> -Outcome Failure -Detailed -Type Connection -starttime 07-03-2020 | Sort-Object endtime | ft

This shows you when the disconnects took place. Maybe it happens exactly the same time, which proves something was wrong in Azure network / WVD gateway / WVD load balancer or broker.

Please let me know!

  Hi,
  
  I've ran the query and indeed 99% of the Failures are on 9/6, customer gave feedback that yesterdag and today go without any issue.
  Of course not all errors may be related to the connection issue. If I do the query on Outcome Failure from 6-3 until today:
  6-3: 3 events
  9-3: 107 events
  10-3: 20 event
  11-3: 1 event

    That seems to be a pattern :). These are our results.
    No problems today and yesterday.
    Was 26th of February also a "bad day" for you?

  Hi, let's get a bit more precise. Last monday, the disconnects happened in batches. Like multiple / all users disconnecting at once.
  
  Just got into the logs, we see this disconnect waves at these times (according to Powershell command result):
  - 11:03:19 AM
  - 11:03:22 AM
  - 11:12:20 AM
  - 11:24:29 AM
  - 11:37:52 AM
  - 13:45:18 PM
  
  Between these times, we also has multiple disconnects for just one user at a time.
  
  I really wonder if you see the exact same times of disconnect waves. That would defenitely prove it's something in the WVD plane.
