Not able to upload image to firebase storage from my App

It has been days facing this problem. Able to the image by the way.Always shows "Upload failed".My app is connected to Firebase Database and Storage. All other values of app are successfully added to the database. But nothing goes in Firebase Storage. Please help.
My Upload activity:

public class UploadActivity extends AppCompatActivity {
    StorageTask uploadTask;
    Uri path;
    StorageReference photoStorage;
    DatabaseReference photoRef;
    ImageView passportsize_photo;
    Button upload_photo, chose_photo;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_upload);

        chose_photo =findViewById(R.id.choose_photo);
        passportsize_photo =findViewById(R.id.passportsize_photo);
        upload_photo =findViewById(R.id.upload_photo);

        photoStorage = FirebaseStorage.getInstance().getReference("Photos");
        photoRef = FirebaseDatabase.getInstance().getReference("Photos");

        upload_photo.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                if(uploadTask!=null&&uploadTask.isInProgress()){
                    Toast.makeText(UploadActivity.this, "Upload in progress", Toast.LENGTH_SHORT).show();
                }else { uploadFile();}
            }
        });
        chose_photo.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                openFileChooser();
            }
        });

    }

    private String getFileExtension(Uri uri) {
        ContentResolver cR = this.getContentResolver();
        MimeTypeMap mime = MimeTypeMap.getSingleton();
        return mime.getExtensionFromMimeType(cR.getType(uri));
    }
    private void uploadFile() {
        StorageReference Ref = photoStorage.child(System.currentTimeMillis() + "." + getFileExtension(path));
        uploadTask = Ref.putFile(path)
                .addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {
                    @Override
                    public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {
                        // Get a URL to the uploaded content
                        //Uri downloadUrl = taskSnapshot.getDownloadUrl();
                        Toast.makeText(UploadActivity.this, "Image Uploaded", Toast.LENGTH_SHORT).show();
                    }
                })
                .addOnFailureListener(new OnFailureListener() {
                    @Override
                    public void onFailure(@NonNull Exception exception) {
                        // Handle unsuccessful uploads
                        // ...
                        Toast.makeText(UploadActivity.this, "Upload failed", Toast.LENGTH_SHORT).show();
                    }

                });
    }

    private void openFileChooser() {
        Intent intent = new Intent();
        intent.setType("image/*");
        intent.setAction(Intent.ACTION_GET_CONTENT);
        startActivityForResult(intent, 1);
    }

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

        if (requestCode == 1 && resultCode == RESULT_OK
                && data != null && data.getData() != null) {
            path = data.getData();
            passportsize_photo.setImageURI(path);
            //Picasso.get().load(path).into(passportsize_photo);
        }
    }
