    Hello there,

    TFTP is considered an unsafe protocol, so Windows does not allow it by default. You will have to either turn off the Windows firewall (which is not recommended) or add an exception on the Firewall for the TFTP Client.

    -Open the Windows Start menu and type “Firewall” > open the “Windows Defender Firewall with Advanced Security,” and run it as an Administrator.
    -Make sure that the firewall is enabled, and click on “Allow an app or feature through Windows Defender Firewall”.
    -Click on “Change Settings,” then “Allow another app”.
    -Click on “Browse” and find the TFTP.exe from the System32 folder and click on Open. Then click on “Add”.
