Hub to robot servers communication issue

[Waqar Mustafa]

Dear All,

 

I am getting following error message while trying to deploy probe on robot server:

 

"(80) Session error, Unable to open a client session for 10.24.xx.***:48000: Connection timed out"

Ports are open b/w hub and robot server, checked via telnet client from Hub to robot on 48000 it works.

 

even when i clicked on spooler or controller probe to view logs, i am getting an communication error message. However when i accessing log files of controller, it shows communication established b/w Hub and robot server.

 

Please help me to resolve this issue.

 

Thanks,

Few confirmations to get better understanding.

 

- Which computer Infrastructure Manager is running on ?

- Does the problematic robot report to a secondary hub or to the primary hub ?
