Issue/Introduction

Agent lost connection to the Automation Engine. When it attempts to reconnect the following message is observed:

CP log:

20200428/213423.763 - U00003412 Agent 'agent name list here' logged on (Client connection='13326').
20200428/213423.767 - U00003366 Connection to agent 'agent name list here' already exists (old connection '*CP002#00000081', new connection '*CP009#00013326')

Agent does not connect and stop generating anything else on the agent log until the agent was shut down by Service Manager or by killing the Agent process. While in this state, AWI shows it as inactive and will not run jobs.

Agent Log:

20200709/101228.868 - U02000004 Connection to Server 'UC4PRD#CP005(ID=3)' successfully created.
