    Hello Yusuf Oezeren

    Welcome to Microsoft Q&A Platform, thanks for posting your query here.

    The error message "ERR_BAD_RESPONSE" indicates that the Serial Console feature is not able to establish a connection with the VM.

    Please try these troubleshooting steps to see if it helps resolve the issue:

    -Check the configuration of the VM and make sure that the Serial Console feature is enabled.

    -Try to restart the VM and see if that helps.

    -Try to stop and start the VM, once the VM is started this will be moved to new host.

    Hope this helps.
