React URLs are not Accessible

问题

hi i've run following command pm2 start process.json on ec2 AWS.

Here is my process.json file

{
  "script": "serve",
  "env": {
    "PM2_SERVE_PATH": './build',
    "PM2_SERVE_PORT": 5000
  }
}

When I run the pm2 command shown above. I can access the Base URL. But when I type the Sub URLs from browser, it shows a page that contains 404 |The requested path cannot be found.

Below is my file structure

I am generating the project using npm run build then pm2 start process.json

So the app starts up and you can access the root page? What about your routes? Are they set up properly? Are you using react-routing or something else?

This sounds like a routing issue. Does it only happen on the AWS platform?

Hi I found a solution to this problem.

When I use serve on pm2 it shows 404 page whenever it didn't find a url resource. To resolve that I used screen on ec2.

To open a new screen type screen Then in your react folder type command serve -s build -p 5000 Now you can detach your screen using CTRL + D
