    @Kang Le,

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

    After recreating the certificates,

    • Please update the Root Certificate in the P2S VPN Gateway
    • Make sure the newly created certificates are properly installed in the OS
    • User's image
    • After this, download the VPN Configuration from the gateway and give it a try again.

    You informed this resolved the issue :)
