This technical document covers a scenario where the primary hub robot is not functioning as expected. 

The symptoms experienced are as follows:

- Unable to connect to the Primary hub via IM. 
- Primary hub nimsoft robot watcher service appears to be lopping. 
- Primary hub logs and robot controller logs display connection or communication errors. 


On further inspection of the Primary hub robot.cfg file, the file appears to be corrupt and / or has missing sections required for the hub to start, and run as expected. 

Example - One or all of the follow sections might be missing or contains incorrect information:

   robotname = 
   robotip = 

   hub = 
   hubrobotname = 
   hubip = 
   hubport = 

In this situation, the "robotname" and "robotip" values were missing. 



Release : 20.3

Component : UIM - HUB
