We are encountering the error message below on one of our vcenter plugins for vRO 7.3.0.5481809. .
https://<vcenter name>:443/sdk (unusable: java.lang.RuntimeException: (vim.fault.InvalidLogin) { faultCause = null, faultMessage = null})
We cannot perform any workflows inside the vcenter. We ran the "Update a vCenter Server instance" workflow using the same administrator@vsphere.local used when adding it. The password is unchanged and is used for four other vCenters. We removed and added back and issue returns. Any thoughts? Where can I look on the vCenter logs for a simular error message?
