Error occurred while proxying request localhost:3000/api/auth/login to http://localhost:5000/ [ECONNREFUSED] (https://nodejs.org/api/errors.html#errors_common_system_errors)

After following the installation steps, I tried to ran the project using the npm run dev command as given in the instruction. The landing page was successfully displayed but when I tried to signed in with the github it didnt forwarded me to the notes page instead a error was thrown

ERROR:
 <e> [webpack-dev-server] [HPM] Error occurred while proxying request localhost:3000/api/auth/login to http://localhost:5000/ [ECONNREFUSED] (https://nodejs.org/api/errors.html#errors_common_system_errors)

Can you please tell me where did I went wrong and what to do to solve the problem?
