Anything helpful information would be appreciable. Thanks in advance.

Solution

  • This happens because you didn't closed that port properly and the connection/port is still running in the background. (Maybe you exited by pressing ctrl+z instead of ctrl+c) You can use this to kill that process:

    sudo fuser -k 8000/tcp

    Note: 8000 is the port number.
