React native axios post request network error on Android physical device

( Note: I am a complete beginner in react native and have gone through a lot of reference searching for a solution and nothing helped.) I am using axios with https url for post request and this is my code.

  try {
  const response = await
      headers: {
        //     //Header Defination
        'Accept': 'application/json',
        'Content-Type': 'application/x-www-form-urlencoded',   // tried application/json
        'X-Requested-From': 'MOBILE',
        'Authorization': 'Basic ' + loginCredential,
  console.log('Success : ' + response);
} catch (error) {
  // handle error

I don't need the body part. I have used the same url with data on android native version and it worked fine. But on react-native I am getting "Error: Network Error" as message without any description. Tried using android:usesCleartextTraffic="true" in manifest.

Any help would be grateful. Thank you
