Follow the steps below to rectify 

1. Deactivate MPSE Probe. (was in Red/Error state) in Infra Mgr. 
2. Delete MPSE Probe in Infra Mgr. 
3. Login direct to host and move MPSE folder to another disk on system. (preserving logs) 
4. Redeploy MPSE Probe via Infra Mgr. 
5. Activate MPSE Probe via Infra Mgr. 

Scenario 2- This is multi ump configuration and the concerned ump server has moved to another hub for any reason 

As per the multi ump configuration
The robot you choose must report directly to the primary hub, and must be on the same network subnet. 
Installing a secondary UMP instance on a robot that reports to a secondary hub is not supported.

In this scenario move the ump server robot back under the primary hub to restore successful communication for UMP
