Yahoo Weather API Working over HTTP but not HTTPS? - php

Question

So I have a website where I want to display the weather. The code I have (shown below) works just fine when I have the $base_url variable set as the following:
$base_url = "http://query.yahooapis.com/v1/public/yql";
But whenever I switch it over to https (shown below) I suddenly get the following error:
Notice: Trying to get property of non-object in C:\xampp\htdocs\scheduling.r60\reports\include\weather.php on line 18
To clarify, I am using XAMPP to test this, but when I test this on a live website, it also doesn't work (the live site does have a valid SSL certificate and HTTPS is enforced).
<?php
$base_url = "https://query.yahooapis.com/v1/public/yql";
$yql_query = "select * from weather.forecast where woeid in (select woeid from geo.places(1) where text='mundelein, il')";
$yql_query_url = $base_url . "?q=" . urlencode($yql_query) . "&format=json";
// Making call with cURL
$session = curl_init($yql_query_url);
curl_setopt($session, CURLOPT_RETURNTRANSFER, true);
$json = curl_exec($session);
// Convert JSON to PHP Object
$phpObj = json_decode($json);
print_r($phpObj);
// Getting necessary content
$cityInfo = $phpObj->query->results->channel->location->city . ", " . $phpObj->query->results->channel->location->region;
$currentDate = $phpObj->query->results->channel->item->condition->date;
