Starting of Rasa Server Failed

I am getting following error while starting the rasa server.

Hello & Welcome @hardik2047 I guess you are using VS Code, this is also a command issue (bind on the address) but normally on my Linux machine not on Window machine. Please close the working terminal (on the terminal in which you seeing this error) and again activate the environment and run the command, basically it’s mean that port 5005 is already in use. Follow this and you will good to go.

I hope this will solve you issue and good luck!
