How to Troubleshoot "Veeam VMware Collector: VMware connection is unavailable"

• Ensure the Collectors are connected to the vCenter
  • On the Collector server, confirm that the ‘Veeam VMware Collector’ service is running.
  • Verify the credentials used by the Collectors to connect to the vCenter are correct.
• Once connectivity is confirmed, consider whether additional collectors are needed. If this error began after adding a host or VMs, it might be necessary. Use the Veeam Management Pack install media for a collector-only installation on a server to see if this resolves the issue. Alternatively, you can deploy the collector through SCOM.

These steps usually resolve the issue, with adding additional collectors being the most common solution. If these steps do not work, please create a ticket with support.
