Casting not Working

I have followed all the instructions for casting my Surface screen to my other Windows PC. I have launched Connect in the target PC and it shows me as "last connected". I have launched Win-K in the Surface and it shows my target PC name and "connecting". But nothing else happens. Don't see the Surface cast on the PC the way it's supposed to. What am I doing wrong?

    Thanks for your feedback!

    Network Settings

    Check if the network settings are correct.

    1. Open Windows Settings > Network and Internet > Status > Properties > Select Public.
    2. Go back to Status > Click Network and Sharing Center > Click Change Advanced Sharing Settings > Guest or Public > Enable "Turn on network discovery" and "Turn on file and printer sharing".

    Firewall

    Check if Cast to Device is blocked by the Firewall.

    1. Press Windows + R > Type "control firewall.cpl" (without quotes) > Click on "Allow an app or feature through Windows Defender Firewall" in the left tab.
    2. Look for the option "Cast to Device Functionality" or similar, and check both checkboxes.

    Hello! How are you?

    Casting depends on your network connection. It may be unstable on your internet or Wi-Fi network. Updates can also cause this problem.

    • Update both computers.
    • Restart both computers.
    • Turn off your internet modem > Wait 1 minute > Turn on your internet modem again.
    1. Open System Configuration > Click ''Update & Security'' > ''Windows Update'' > ''Check for Updates''.

     

    1. Download all available updates. Click on the ''Show optional updates'' option (marked in blue) if you have > Select all drivers > Click on ''Download and Install''.
