Guzzlehttp\Exception\ConnectionException: cURL error 28 resolving timeout after 2851 milisecond

I have recently integrated Algolia with my laravel application using Laravel-Scout library. Whenever, I try to search to search any products using algolia, I get GuzzelHttp\Exception\Connection\Exception. Following is the screen output of the response. I have doubled checked my Algolia credentials in my project and they match correctly. I am running this project in linux mint-18.04 LTS, using default laravel server (neither Apache nor Nginx) and MySQL server.
