Axios image upload using post form data always returns network error

Having problem uploading an image on android running react native using axios. I have researched a lot about this and have tried a lot of things for the past 3days but no solution yet. This seem to be a very common problem on android. Any help is appreciated.

let url = "myURL will be here"
let uploadBody = new FormData()
uploadBody.append('photos',{uri:this.state.coverImage[0].uri,type: 'image/jpeg',
    name: 'coverimage'})
axios.post(url, 
{
method: "POST",
body: uploadBody,
headers : {
"Content-Type":"application/x-www-form-urlencoded"
}
}).then((resp) => {
console.log(resp);
}).catch(err => {
console.log(err);
});

The api works fine on postman. I am able to upload images. And i get a response { "success": true }

Getting this error on android
