I am trying to run my react app I tried with all the below command:
“npm start”; “npm run start /force”; “npm run start –verbose”.

[email protected] start
react-scripts start –PORT 3000

http://localhost:3000/
http://localhost:3000/webevents

This site can’t be reached
localhost refused to connect.

I checked the firewall and the my internet connection and the environment variables everything is correct.

the code is running normally on other PCs
