I have error in running the rasa shell command

@Nithin07-crypto Hi, can you please share the rasa --version.

rasa version @nik202

Is maybe something else already running on this port / is the firewall blocking something?

@Tobias_Wochinger This is more persistent issue, I even update the port in the socket.py and then this error is gone, but related to task-2, task-8 and 9 is more persistent on the forum.
