Login Error: There is an error in logging you into this application. Please try again later

I am getting this error. When I try to sign in with facebook to my app. When I first time authentication it will correctly working. After I unistalled my application and now trying to sign in with Facebook on that I am getting this error.

Another Issue : After authenticate in device1 and try to login with facebook on device2 also same error is getting.

Solution I Found : when I remove App authentication from Facebook App Settings it is working in above scenario's but this is not an good solution how we can tell to users to do this action?

btnFbLogin.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                if(accessToken != null) {
                    boolean expires = accessToken.isExpired();
                    if(!expires) {
                        performFbLoginOrSignUp(accessToken);
                    }
                } else {
                    LoginButton loginButton = (LoginButton) findViewById(R.id.login_button);
                    callbackManager = CallbackManager.Factory.create();

                    if (loginButton != null) {
                        loginButton.setReadPermissions("public_profile", "email", "user_friends");

                        if (CommonUtil.isConnectingToInternet(LoginActivity.this)) {
                            loginButton.performClick();

                            loginButton.setPressed(true);

                            loginButton.invalidate();

                            loginButton.registerCallback(callbackManager, mCallBack);

                            loginButton.setPressed(false);

                            loginButton.invalidate();
                        } 
                    }
                }
            }
        });
