Uploading image doesn't work in firebase cloud storage

Question

I'm having trouble uploading an image to firebase cloud storage. I get no errors/warnings, the upload just doesn't seem to work! Both the Toasts are not showing either, the app just sits idle and after a while shows "connection refused.." in the logcat.

Here's the code snippet :

    private Uri fileUri;
    private StorageReference storageReference;
    private UploadTask uploadTask;
    private String myurl = "";


    private void SelectImage()
    {
        Intent intent = new Intent();
        intent.setAction(Intent.ACTION_GET_CONTENT);
        intent.setType("image/*");
        startActivityForResult(Intent.createChooser(intent, "Select Image"), 420);
    }



    @Override
    protected void onActivityResult(int requestCode, int resultCode, @Nullable Intent data) {
        super.onActivityResult(requestCode, resultCode, data);

        if(requestCode==420 && resultCode==RESULT_OK && data!=null && data.getData()!=null)
        {


            fileUri = data.getData();
            storageReference = FirebaseStorage.getInstance().getReference().child("Image Files");
            final StorageReference filepath = storageReference.child(nameString+".jpg");



            uploadTask = filepath.putFile(fileUri);
            uploadTask.addOnFailureListener(new OnFailureListener() {
                @Override
                public void onFailure(@NonNull Exception exception) {
                    Toast.makeText(MessageActivity.this, "Failed", Toast.LENGTH_SHORT).show();
                    // Handle unsuccessful uploads
                }
            }).addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {
                @Override
                public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {
                    Toast.makeText(MessageActivity.this, "Uploaded Successfully!", Toast.LENGTH_SHORT).show();
                    // taskSnapshot.getMetadata() contains file metadata such as size, content-type, etc.
                    // ...




                }

            });


        }
