Expo Authentication Error getaddrinfo ENOTFOUND 3128 3128:80

[sarlken]

I’m kinda new to Expo and I would like to launch my React code on the emulators of Expo. To do that I’ve installed everything like npm, node.js, expo, yarn and all.

I use my corporate network to connect to internet so for almost anything I need to do proxy settings… So I’ve configured the proxy settings of npm and I can see these settings when I typed the following commands: npm config get proxy npm config get http-proxy and all no problem.

When I launch expo start, everything goes really well till the point below:

I’m getting the error below: Error: getaddrinfo ENOTFOUND 3128 3128:80

Every help will be appreciated!

Today I have realized that this problem got solved I can see the application on my phone after doing ‘expo start’ and logged into my account but when I click to the application, I cannot access to the project. It says “there was a problem running the requested app” on expo-cli application on my iphone.

Hey @sarlken,

Can you ensure your device and computer on the same network? Also, what host are you using (tunnel, localhost, lan)?

Cheers,
Adam
