Azure P2S VPN client disconnects exactly every hour

@Scott M , @Jaap van Lenthe , @Sameer Patel @Bob Beatty

Thank you for reaching out. I am following up on a similar issue internally.

Can you please confirm the Azure VPN client version you are using?

You can check the version as below.

This issue can be related to Azure VPN client version 3.1.2.0. The work around in this case is to downgrade your VPN client to version 2.2159.179.0

Please let us know if this helped in resolving the issue. Thank you

I am using the version you show which is the one from the Microsoft Store.

I guess I will tell you in an hour if that works!!

Thank you for the prompt reply!

Yes, the older version seems to be working for me at least. Will get the other users to try it out.

Confirmed, the tunnel has not dropped since I downgraded to the previous version.

It's not really an answer though is it, its a temporary workaround. Having to get every user to manually install this version is a royal pain.

My appologies- I did not mean to mark it as an answer - (middle of the night). I completely agree with you, it is a pain - hopefully, lots of users have not upgraded their client.

This is believed to be a DNS Issue. Do NSLOOKUP on the VPN Host shown in Azure VPN Client, then add that IP and host name to the hosts file on the client PC. This should clear the issue with the dropping every 1 hr with the 'No Such Host Found' error in the log. Our theory is a windows update pushed this issue out about a week ago.

Thanks Robert, I have tried this, but this still disconnects your VPN at an hour count, its just that it reconnects almost instantly, not an idle permanent solution.

Adding info to host files is not an answer. Its still a bandaid/workaround.

Will the store update back to the latest version?

So There is a known issue with P2S VPN CLIENT version 3.1.2.0 that causes P2S intermittent disconnections.

Mitigation is to advice Cx to unistall the P2S VPN CLIENT 3.1.2.0 and downgrade to Version 2.2159.179.0 using this link to donload and install the the downgraded version VPN client to version 2.2159.179.0

Azure P2S VPN client disconnects exactly every hour - Microsoft Q&A

Aren't the store updates automatic? This is causing a lot of issues with our users, and we are waiting for Microsoft to provide a fix.

the link does not work

App updates in the Microsoft store are turned on by default, which causes the Azure VPN-client app to update automatically. It is possible to turn off manually through the store. We the ones who manage devices centrally can turn this off through a Powershell and send the policy via Endpoint Manager (Intune), AD via GPO or other UEM solutions that can execute PowerShell to devices. It is not the best solution as it turns off automatic updates for all apps. Maybe there's a better solution here that only prevents updating for the Azure VPN-client, anyone? Even if the app update is turned off, users can manually update it by visiting the Microsoft store but this is a solution that works for me. This works for Windows 10 and 11.

$Path = "HKLM:\SOFTWARE\Policies\Microsoft\" 
$KeyName = "WindowsStore" 
$ValueName = "AutoDownload" 
$Value = 2 

# Create the registry key "WindowsStore"
New-Item -Path $Path -Name $KeyName -Force | Out-Null 

# Enter the REG_DWORD value "AutoDownload" with a value of 2 under "WindowsStore"
Set-ItemProperty -Path "$Path$KeyName" -Name $ValueName -Value $Value -Type DWORD

We are based in NZ. Azure production systems hosted in Melbourne. Staff on version 3 of Azure VPN Client dropping every hour. Exactly every 60 minutes.

Microsoft support have informed me they will be rolling back the released version to the 2.xx version later today. What this means for people that already have the 3.xx version I don't know. I guess at worst they can uninstall and reinstall it via the store.

Any updates with the rolling back of the released version to 2.xx? i go to the store and 3.1.2 is still available. trying to avoid having to uninstall and reinstall 500 clients. is there way better and efficient solution?

Same issue, once an hour, everyone in the company. You can see in the event log for the RasClient

The user AzureAD\xxxxxxx dialed a connection named xxxxxx which has terminated. The reason code returned on termination is 829.

The update to Version 3:1:2:0 coincided with the problem arising. So indeed the new version of the client seems to be the issue.

It would be good to understand a long term fix for this, rather than downgrading every client

Experiencing the same. Commenting to follow the updates.

version 3.1.3 is now available in the store, has fixed the 1 hour disconnect issue. apply the update. if you manually downgraded you will have to uninstall and reinstall from the store. this was based on a few testing scenario i did. no word yet when microsoft will push it out automagically, expecting soon

I've updated to 3.1.3 manually and will test with a few clients.
