We are trying to monitor a vCenter 5.5 resource under the vmware probe. The vCenter uses TLS 1.0.
Release: 20.4
Component: UIM - VMWARE
This was a case where the probe itself supported fall back to TLS 1.0, but the version of the java_jre package on the robot is 2.09. Starting with version 2.07, all communication was set to TLS 1.2 with no fallback.
Revert to java_jre 2.06 or set TLS to 1.2 for the ESX server in this case, or other source with other probes.
