    @DG001

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

    You informed that you are facing issues with S2S Connection in a vWAN. "Negotiation timed out" indicates that the peer (OnPrem) did not respond to the Azure VPN Gateway negotiation packets.

    • I requested you to check the logs from the OnPrem VPN device and check whether or not packets from VPN Gateway reached the VPN Device?
      • If yes, why the VPN Device did not respond to VPN Gateway packets?

    However, you informed that the issue has been resolved.

    Please don’t forget to close the thread by clicking "Accept the answer" as this can be beneficial to other community members.

    Cheers,
