Unable to Connect iOS Device to Intune Tunnel VPN

Question

Hello team

I have set up an Intune Tunnel from Intune to on-premises, and the tunnel status is showing as healthy. I’ve also deployed the VPN profile to the iOS app.

However, when I try to access the tunnel:

• The VPN connection doesn’t seem to work.
• The Edge browser is unable to connect to the tunnel VPN and has no internet access.
• I’m also encountering the following error:

I’ve tried troubleshooting but haven’t been able to resolve the issue. What steps should I take to fix this?

@Anant Bera, Thanks for posting in Q&A. From your description, I know the error: "Tunnel can't connect, please sync with company portal" occurs on iOS device.

To clarify the issue, please check the following information:

1, Please ensure manage.microsoft.com and *.manage.microsoft.com should be allowed in firewall. 

2, Sync with Company Portal: Make sure that the device is properly synced with the company portal.

3, How many iOS devices are affected? Does it affect all? Verify that the VPN profile deployed to the iOS app is correctly configured. https://learn.microsoft.com/en-us/mem/intune/protect/microsoft-tunnel-configure#create-a-vpn-profile

4, View Microsoft Tunnel logs to see if there's any finding.
