Hybrid Search - Onboarding Cloud SSA Error

Hello everyone - thank you for taking time to read my post. I'm struggling to fix the following issue that I'm facing while running Onboard-CloudHybridSearch.ps1. The error message is occurring when the script is trying to get Service Info from Office 365. Your help is appreciated.

Error Message: 

Exception calling "ExecuteQuery" with "0" argument(s): "The request channel timed out while waiting for a reply after 00:02:00. Increase the timeout value passed to the call to Request or increase the SendTimeout value on the Binding. The time allotted to this operation may have been a portion of a longer timeout."
