const url= `http://127.0.0.1:3000/api/info`
await RNFetchBlob.fetch('GET', url, {});

when running it on IOS virtual device, it works fine, running it on Android virtual device, if set url with http://127.0.0.1:3000/api/info , get an error: Failed to connect to /127.0.0.1:3000 if set url with http://localhost:3000/api/info , get an error: Failed to connect to localhost/127.0.0.1:3000

@liushmh brother you can set IP address local can't localhost , change localhost to IP address

Thanks @dhamdani666

@PAVITHRA88 how did you solve this in details

Afaik on Android you need to reference 10.0.0.2 in order to point to the host machine's localhost (from Android simulator). 127.0.0.1 is the virtual phone's localhost
