    Hello,

    Thank you for posting in Q&A forum.

    Please try below steps and see if it helps on this issue.

    1. Make sure that the SSL/TLS certificate for WebSocket (wss://) on Windows Server is configured correctly.
    2. You can also check if private key associated with the SSL/TLS certificate is accessible and valid.
    3. Check if the account used to run the ISS application pool has the permission to access the private key.
    4. Restart the ISS service and see if it works.
