I faced the same issue. You can resolve this by killing the process running on 5005 port. Steps to kill the process: **WINDOWS** 1. find the PID number by running: `netstat -ano | findstr :5005` 1. Enter PID number below to kill the process `taskkill /PID 5005 /F` **MAC** 1. `kill $(lsof -t -i:5005)` Source: [cmd - How do I kill the process currently using a port on localhost in Windows? - Stack Overflow](https://stackoverflow.com/questions/39632667/how-do-i-kill-the-process-currently-using-a-port-on-localhost-in-windows) ---

Thanks. when i run this in command line --\> netstat -ano | findstr :5005 C:\Users\mjeevaba\>`netstat -ano | findstr: 5005` ‘findstr:’ is not recognized as an internal or external command, operable program or batch file. also failed `taskkill /PID 5005 /F` although i can find the PID for port 0.0.0.0:5005 by running netstat -ano it was some number like 32145 changed the command `taskkill /PID 32145/F` the ask got killed. thanks for resolution but why findstr was not working? ---

Glad I was of help. Maybe this command would work: ```auto netstat -a -n -o | find "123456" ``` I do not have windows installed so I cannot check it. ---

thanks, it worked. Need to capture the PID and kill it! Usually its because multiple RASA servers are running. ---
