Welcome to the Microsoft Q&A Platform. Thank you for reaching out & I hope you are doing well.

I understand that you are loosing internet connectivity once you connect to your Azure P2S VPN from a remote device.

Tunnel type: IKEv2 and OpenVPN(SSL)

Authentication type: Azure certificate

Can you let us know about the below?

Is this a Windows Device?

Are you able to reproduce the issue with a different device ?

Are you using Azure VPN Client from the Store App?

https://apps.microsoft.com/detail/9NP355QT2SQB?hl=en-us&gl=US

If not, please use this and import the Configuration file

Did you try re-downloading the VPN Configuration file and importing it?

How are you confirming that Internet connectivity is lost?

Is the Wifi connectivity symbol disappears

Or you are connected to the Wifi but you do not have internet access?

Cheers,

Kapil

Yes it is a window device. I have other VPN it is working with that. I have issue with Indian VPN. I am directly using the VPN server URL and configure VPN in my system. Yes I have re installed the VPN. Yes I am connected to the Wifi and I do not have internet access on the system. But I am able to access the VM.

This could be because of misconfiguration in the VPN Configuration.

I would suggest you use the Azure VPN Client from the Store App and see if the issue persists.

https://apps.microsoft.com/detail/9NP355QT2SQB?hl=en-us&gl=US

See : Download the Azure VPN Client

And let us know if this works or not.

In case the above did not help, we could proceed further by checking DNS

Connect your device to the P2S VPN and open a Powershell window as Admin

Run nslookup www.bing.com

Run nslookup www.bing.com 8.8.8.8

Run tnc www.bing.com -p 443

And share the results.

Cheers,

Kapil

Hi Guys,

I've tested this issue.

Steps performed:

New Azure VPN config downloaded from the Azure Portal VPN Gateway P2S (doesn't work)

Checking of ipconfig /all , route print, tracert, nslookup, test-netconnection, telnet, wifi/wired interfaces settings (all checked, no issues)

The problem is somehow related to the the Microsoft EDGE web browser DNS settings. When open Microsoft EDGE -> Settings -> search for "dns" -> look for "Use secure DNS to specify how to lookup the network address for websites". By default there is a settings set "Use current service provider". To solve the case and have the internet connection while on Azure VPN select "Choose a service provider", click in the empty field below and select e.g. "Cloudflare (1.1.1.1)". It will appear as "https://chrome.cloudflare-dns.com/dns-query". Screens attached. Then reboot the web browser - Microsoft Edge - and the internet will start to work right away.

Security info: In this Cloudflare DNS is used to resolve your DNS queries. If you do not want to do that try with your own DNS servers or other DNS you prefer in this step.

NOTE: If this will help you feel free to leave short comment or just share this to other that have such issue.

In case of questions feel free to let me know via comments as well.

Best regards,

Tomasz Wieczorkowski

The error "Status = VPN Platform did not trigger connection" is generally a client-side issue or most likely a bug in the Windows VPN platform. But mostly this error appears when the Azure VPN Client does not have the "Background apps" App Permission enabled in App Settings for Windows.

You can follow the below steps one by one until one of them fixes the issue:

1.

Could you please make sure that the Azure VPN Client has permission to run in the background.

In Windows, select Start, then select Settings > Apps > Apps & features or Installed Apps.

Scroll to the Azure VPN client, select More options on the right edge of the window, then select Advanced options.

In the Background apps permissions section, under Let this app run in the background, select "Always".

2.

If the above did not help, try the below steps:

Make sure that your Windows OS has all the required updates/hotfixes installed.

Delete/Uninstall all WAN miniport network adapters from Device manager, and then click on Action > Scan for hardware changes or perform a machine restart.

3.

In case the above persists, Restart the Rasman service

You must be an Admin to do this

Click Start, click Run, and then type services.msc & hit enter.

Right-click the Remote Access Connection Manager service and then click Start/Restart.

Cheers,

Kapil

@Arunkumar Venkatesan

As next steps,

Can you please check if the local time is synchronized (correct) in the affected machine?

If not, make sure the time is updated.

Can you check if the user is able to log in using the same credentials from a different machine?

Thanks,

Kapil.
