Hello Scarlett Liu

I understand that you're experiencing the "VPN Platform did not trigger connection" error with your Azure VPN Client on your ROG device running Windows 11. Since another device can connect using the same XML profile, it seems this issue may be related to the configuration or settings on your ROG.

Here are a few steps you can follow to troubleshoot the issue:

Ensure the Azure VPN Client has the correct background app permissions:

Go to Settings → Privacy → Background apps and toggle "Let apps run in the background" to On.

Outdated drivers can sometimes cause connection issues. Open Device Manager, find your Network adapters, right-click on your adapter, and select Update driver.

Even though you mentioned allowing the app through the Windows Defender Firewall, double-check by going to Control Panel → System and Security → Windows Defender Firewall → Allow an app or feature through Windows Defender Firewall, and ensure Azure VPN Client is listed.

Verify your certificates are properly installed: the AzureClient.pfx certificate should be in Current User → Personal → Certificates store, and the AzureRoot.cer should be in Local Computer → Trusted Root Certification Authorities.

If you are experiencing issues with WAN Miniports automatically recovering, it may indicate a driver or configuration issue. Check if resetting the network settings might help.

Check the Event Viewer for additional logs that might provide more insights into what is happening when the connection is attempted. Look under "Applications and Services Logs" for the VPN client logs.

Consider running a network reset by going to Settings → Network & Internet → Status → Network reset.

Dear Scarlett Liu,

Thank you for reaching out and providing detailed information about the issue you're experiencing with the Azure VPN Client. Based on the logs and troubleshooting steps you've shared, here are some additional suggestions to resolve the "VPN Platform did not trigger connection" error:

First, double-check the VPN profile configuration to ensure the XML profile is correctly imported and matches the configuration required by your Azure VPN Gateway. Even though it works on another device, there might be device-specific nuances.

The automatic recovery of WAN Miniports suggests a system-level problem. Try resetting the network stack by running the commands "netsh winsock reset" and "netsh int ip reset" in an elevated Command Prompt, then restart your device.

Verify that all dependent services are running, including Rasman, SstpSvc, vaultSvc , and WinHttpAutoProxySvc.

Check the Event Viewer for detailed error messages under "Applications and Services Logs > Microsoft > AzureVpn" to identify any underlying issues not captured in the status logs.

Ensure there are no Group Policies or registry settings blocking VPN connections. Look for policies related to VPN or network restrictions that might interfere with the connection.

If possible, try switching to a different VPN protocol (e.g., IKEv2 instead of SSTP) in the Azure VPN Gateway configuration to see if the issue persists.

Performing a clean boot might help rule out third-party software interference. Instructions for this can be found on Microsoft's support site.

As a final step, consider deleting the existing VPN profile and recreating it from scratch, ensuring all settings are correctly applied.

If the issue persists after trying these steps, please provide the Event Viewer logs or any additional error messages for further analysis.

Alex
