I have set firewall push rules and only allowed ports 3389, 3391, and 443 to be connected to remote services. If you disable these rules, you can connect normally.User's image

    Thanks for posting your question in the Microsoft Q&A forum.

    Double-check that the firewall rules are configured correctly. Ensure that the rules allow inbound traffic on the server and outbound on the client for specified ports (3389, 3391, and 443). (I think you set inbound traffic on the client)

    And at last verify that the rules are associated with the correct network interfaces.

    Hello, Hosts port should be 3389 3391 443 by default. The error means you may have a network issue.

    Possible reasons:

    If everything is fine, try to capture a network log like wireshark.
