Issue/Introduction

When adding a vCenter data source to Aria Operations for Networks environment, you may receive the error "VMware vCenter: Hostname/IP is unreachable" despite one or more of the following:

• Successfully added other vCenter servers.
• Have the same permissions as the successful vCenter server and/or confirmed permissions per the documentation
• Tried both FQDN and IP address with the same results
• Can ping and do NSLookup from both collector and platform devices to the vCenter servers
