Issue:

After turning on SSL Mode on the primary hub UMP is no longer connecting to the primary hub.

In the UMP controller.log we see

Dec 20 15:32:27:867 [139895203563264] Controller: sockConnect - SSL connect to 10.1.1.1/48002 failed

We also see high CPU usage on the primary hub and some probes are not gaining a port number.

Environment:
Unified Infrastructure Manager
Cause:

At this time, only "Normal" SSL mode is supported on the primary hub. Certain probes on the primary hub and UMP server are unable to connect via SSL which will prevent them from starting.

Resolution:

When SSL mode is activated, it will propagate to connected robots and modify their robot.cfg

 

In the UMP's robot.cfg please change the following keys to match:

   ssl_mode = 0
   ssl_cipher = DEFAULT

Then restart the primary hub robot and the UMP robot.
