PHP - Connectivity Error Or Security Certificate Issue ?

Hi folks,

a few days back, we enabled SSL on our office server and the intranet migrated to https. Everything is ok on the intranet.

On the public internet, we noticed today that the page on our website, which connects to our office server to fetch and display data was throwing an error, which I presumed was a Security Certificate issue... An area that's like the Dark Side of the Moon for me..

the webpage - https://liveconnections.in/hotjobs.php

This is the error from the logs

 PHP Warning: file_get_contents(): SSL operation failed with code 1. OpenSSL Error messages:
error:14090086:SSL routines:ssl3_get_server_certificate:certificate verify failed 
PHP Warning: file_get_contents(): Failed to enable crypto 
PHP Warning: file_get_contents(): SSL operation failed with code 1. OpenSSL Error messages:
error:14090086:SSL routines:ssl3_get_server_certificate:certificate verify failed

Anycase, the internet was willing to help and so I updated the code to a curl function. The Data is not displaying still...

However, when I try to access the office server by loading the php page in my localhost, the data is displayed.

Here's the code... where am i going wrong ?

Also, if i change the $url in my code to https:// , no data is displayed...

I raised a Support request to the Hosting provider, but they seem to have vanished into the ozone....

Any help would be highly appreciated.
