Problem with chatbot using rosa

Everytime I run the scripts: rasa run actions, there was always an error “OSError: [Errno 10048] error while attempting to bind on address (‘’, 5055): only one usage of each socket address (protocol/network address/port) is normally permitted”. The debugger told me that it is from …/asyncio/ However, I don’t know how to fix this. Can anyone help me? P/s I’m using python 3.8 and rasa 2.3.4

Maybe you are running another application or chatbot in the 5055 port, that’s why you are not allowed to run in the same port.

Thanks. But this was the first time I use Rasa so I’am pretty sure that there was no app using 5055 port.
