Hi @MohankumarAmbati

It looks like your gatsby develop is trying to run on an external IP address (218.93.250.18) rather than your local machine. Is this something you have purposefully done, or has it just happened automatically?

You could try forcing it to use localhost (127.0.0.1) by running this command

gatsby develop -H 127.0.0.1

Seems like a reasonable assessment, thanks @andrewfairlie!

One additional note is that if you are passing anything custom there, you can also just remove it, e.g.

"scripts": {
  "develop": "gatsby develop"
}

and running npm run develop will open up a development server at http://localhost:8000

Going to close this as answered-- @Mohammed-Alama feel free to re-open or reply further if we can help with this or if this doesn't seem to fix the issue.

Thanks man @andrewfairlie your solution by forcing to use localhost is working well ,and it just happened automatically ,another questions how to make it run by typing gatsby develop instead of
gatsby develop -H 127.0.0.1

@Mohammed-Alama what setup are you working with here? Is this running in a VM by chance?

You should be able to use gatsby develop -H 0.0.0.0 as well, and that will make it routable from the outside world.

It's possible this could be a bug in gatsby--but can't validate that until I know more about how this is working currently in your setup!

it's working on my local machine and i have try gatsby develop -H 0.0.0.0 and it also working will
but can't using gatsby develop ever
