React development server disconnected problem

Excuse me. I’m confused. I downloaded the CRA from the old way also it’s working at the chrome.

Are you an “IT Crowd” fan too?

  1. If you installed it with something like create-react-app ProblemForReactJS, then that sounds like the old way. I would uninstall CRA and use the method described here.
  1. If Chrome is working, that may be an indication that we’re on the right track.

Okay, thanks, ı gonna try.

And you don’t have to give up your old projects - you can just copy the src folder from the old project into the new, reinstall your dependencies, and it should work.

This is not working.

Well, did you say it worked on Chrome? In either case, my next step would be to make sure the browsers are updated.

Yes, i Said but ı dont use Google Chrome. it’s not working the other browserse (edge, firefox) that’s mean literally not working also my browser is currently.

I don’t see where you said that. I see:

If you have a browser that is working, why not use that? Chrome is a popular and dependable choice. I might stay away from Edge as my default dev browser. FF should be OK - I’m not sure what the problem is there.

In any case, you have an issue here. As near as I can tell, it is one of a few possibilities.

  1. Your setup isn’t making the server properly.
  2. Your browser isn’t talking to the server correctly.
  3. You’re doing something that is interfering.

If we ignore the last one, then we’re left with making sure your project gets set up properly or making sure you have the most current browser. That is what I’m trying to get you to verify but I feel like I’m pulling teeth here so I guess I can’t help you.

My only advice is to make sure that everything is up to date and start scouring google and stack overflow for those error codes.
