Laravel Request does not return result - php

Question

I am using AWS and laravel 5.1.
I have two issues:
Most of the time API returns the expected result but sometimes server
doesn't return result for longer time. It might be due to the server
load(Although we don't have too much load on server).
Clients wait for few minutes and after that application crashes. Any
Advice.
If Client made an API request and before getting result, if device
loses internet connection. Server has process the data but unable to
deliver it to the client. how to handle this (Both in get as well as
post request)
Sample Code for first Part
public function psychometricResponses(Request $request)

$questionId=$request->get('questionId');
$answerId=$request->get('answerId');

$email = $request->has('email') ? $request->get('email') : '';
$gender = $request->has('gender') ? $request->get('gender') : '';
$relationshipStatus = $request->has('relationshipStatus') ? $request->get('relationshipStatus') : '';

$status = 1;
