Unable to discover anything on Vcenter using insight discover

[Alessandro Paggi]

Hello, I have this issue and I cannot find a way to troubleshoot.

We have jira software with insight and insight discovery plugin. I configured a discovery job, using ESXi_Virutalmachines.pat and ESXi_Hostsystems.pat using credentials like admin@vsphere.local. Checking credentials response is OK, so software can connect to vcenter. By the way, when discovery is launched, I have this log:

Why discovery can't find any information from vcenter?

Thank you all
