VPN with AD auth

Mahmoud Habib 20

I create VPN with AD auth but I receive this message when I connect

Dialing VPN connection master-node-vnet, Status = A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond.

Hi Mahmoud Habib

There can be multiple reasons why you can't achieve the VPN connection, and a troubleshooting can help on this. I would suggest the following steps:

Reset Virtual Network Gateway: For resetting the Gateway, you may open the following 'Reset' button in your VPN gateway blade. If the above reset is not helping, more troubleshooting may need as below

Enable Azure VPN Diagnostic Logs to get more details. Check the P2SDiagnosticLog to get more details of the root cause.

You may also set-up a packet capture for you VPN Gateway to reach the exact issue

Hope this helps.

Have you checked, if any firewall connection is blocking the successful connection between the workstation and azure premises? Any chance to check the connection from another workstation?

You may try uninstalling and re-installing the network components as explained below:

Open Computer Management > "Device Manager"

Network Adapters > Right-click, uninstall all adapters starting with "WAN Miniport"

Select "Scan for Hardware Changes" from the menu to reinstall the adapters automatically

Try connecting to the VPN again and see if helps!

Do you have any other components that blocks the successful connection like for example Intune? If so, please make sure that you have added necessary rules to bypass those restrictions

Hello Mahmoud Habib

Greetings!

I wanted to check if you have reviewed the update from Manu Philip

Additionally, could you please re-download the client VPN, verify the client VPN certificate, and ensure the AAD configurations are correct?

We request you to perform a ping test from on-premises to Azure and check the gateway IKE logs.

Once Computer Management Opens, click "Device Manager"

Under Network Adapters, uninstall all adapters starting with "WAN Miniport" - Right-click, Uninstall

Can you please confirm whether you are able to connect to the VPN on another machine using the same user? If the same user can connect on another machine but is unable to connect on the current one, you can follow the steps mentioned in the link below, which address the same issue I discussed earlier.

Hi @Mahmoud Habib

Welcome to the Microsoft Q&A Platform.

Thank you for reaching out, & I hope you are doing well.

You can check the same user on different working machines. If the user is able to connect on another machine, there might be an issue on the system side.

You can try deleting the VPN profile and downloading a new one.

Once you have a working profile and need to distribute it to other users, you can export it using the following steps:

Navigate to VPN client profile that you want to export and select the VPN profile, then select Export option.

Select the location that you want to save this profile to, leave the file name as is, then select Save to save the xml file.

If you are still facing an issue, you can follow the steps mentioned in the link related to the same issue.

You can also check if any firewall, Intune policies, or group policies are blocking the VPN server

Reference: Export and distribute a client profile

I hope this helps to resolve your issue.
