I have tried few solutions, but no luck.

EDIT: Additional info enter image description here

I have changed the react native port to 8088 and modified it in project.

Solution

  • How I fixed the issue?

    Get the process running in the port 8081

    sudo lsof -i :8081

    and killed it.

    sudo kill -9 336

    *336 is the PID (Process ID)
