Credentials created/used for vRanger to access vCenter show as failing from the Tasks/Events screen in the vSphere Client, but all tasks within vRanger are running successfully.
The failures are happening every second and causing problems with the vCenter server. vRanger was once installed on the vCenter server but has since been removed and installed elsewhere.
In the Tasks/Events screen the error references the vCenter server as attempting to use these credentials, not the new vRanger server
The KB below will provide the solution to this issue.
