getaddrinfo ENOTFOUND exp.host

even I open expo.host from the browser loading.. I tried using 2 internet providers, change dns, flush dns, etc. still not loaded.

Answer 1

I solved this by deleting all expo related files and folders in my project .expo and .expo-shared specifically. when you run expo start, expo will automatically regenerate those files. Make sure you are connected to the same network as your phone and PC, you can try signing in and starting the project from your recent development tab on expo client.

if this dosen't work try reomving some devDependencies that you're not really using, then delete the node modules and install afresh.
