typeerror: failed to fetch react native

I'm trying to receive some simple json from mocky.

React native fetch function:

getMemberDomainList = async (name) => {
  try {
    let response = await fetch('', {
      method: 'POST',
      headers: {
        Accept: 'application/json',
        'Content-Type': 'application/json',
    let responseJson = await response.json();
    return responseJson;
  } catch (error) {

I have tested the address in chrome on windows, it returns the expected mock data. But when the function is called on my android phone I get this error

Error from remote debugger

I'm also running a WebView in my app, which is pointing to a web url, it loads perfectly so I am sure that the phone has internet permission and access etc.

  • it could be because of http ... https is needed
  • in your remote debugger ... what did this console.error(error); print ?
  • remote debugger not workin unfortunately. But good point on the https, will try another mock service and see if that resolves it
  • switching to a https mock api seemed to make a difference, at least the stack trace looks a bit different. Same error though "network request failed"
