Email Connector Error - POP3

I have integrated the Email Connector module within my application and have no problems receiving emails via a POP3 Gmail configuration when testing locally. However, when trying to emulate the same on my cloud test environment, I am encountering an error.   I’ve debugged when using local and cloud test environments and the ‘isConnected’ boolean that is returned from SUB_EmailAccount_CheckServerConnection seems to return false doing the cloud testing as opposed to the local testing which returns true. Any ideas as to how to fix this issue?
