Veeam : How to resolve Unable to connect to VBR Server:10006 when you deploy AHV proxy appliance

Veeam has released a new version of the AHV proxy appliance NutanixAHVPluginProxy_2.0.558 with a lot of new features that give you more control over backup and restore jobs from the Veeam Backup & Replication (VBR) console.

You might experience a few problems when deploying the new Nutanix proxy appliance with an error “Failed to Deploy AHV proxy VM: Failed to deploy Proxy – Backup REST error: HTTP StatusCode:BadRequest’, Description:'”Unable to connect to VBR Server:10006”, and the Nutanix plugin installed on the VBR server deletes the new appliance before you can even troubleshoot the problem.


The first step to troubleshoot this problem is to test the port 10006 on your VBR with this command:

Test-NetConnection VBR-IP -Port 10006

  • ComputerName :
  • RemoteAddress :
  • RemotePort : 10006
  • InterfaceAlias : Ethernet
  • SourceAddress :
  • TcpTestSucceeded : True

If you are able to connect to your VBR then the problem is not the network and you need more troubleshooting.

The log file of the AHV plugin installed on the VBR server can be found on the VBR server C:\ProgramData\Veeam\Backup\Plugins\AHV. So you can find all the step of the integration between the VBR server and the proxy appliance which can be summarized on the steps below:

  1. Verified that no registered proxies found.
  2. Upload proxy image files
  3. Created the proxy appliance
  4. Powering ON VM – Getting an IP of the VM – Update credentials data for proxy – Apply new configuration for proxy VM
  5. Adding Nutanix cluster
  6. Adding the VBR server
  7. Remove the proxy appliance from Nutanix cluster

On step 6, the proxy performs a rest API call to register the VBR server with the DNS record of the VBR server. So the DNS zone where the Veeam Backup & Replication server is located must contain a DNS resource record for the AHV Backup Proxy server otherwise the deployment will fail. 

Workaround :

If you don’t want to add a DNS record for the AHV Backup Proxy server, you can add the hostname of the proxy appliance on your VBR server C:\Windows\System32\drivers\etc host file and the hostname of the VBR server on the hosts file in the proxy appliance /etc/hots and you can use the following workaround.

STEP 1: Add hostname of the proxy appliance on your VBR

STEP 2: Deploy and configure a new Nutanix backup proxy from the VBR console

STEP 3: Open the log file C:\ProgramData\Veeam\Backup\Plugins\AHV with Notepad++ and Nutanix Prism element console

STEP 4: When you have info on the log file about the configuration of the proxy had been saved take Nutanix snapshot for the new VM deployed.

2020-03-27 12:39:29.123 00005 INFO | [AhvProxy]: Configuration for proxy [DnsIp:’’, Port:’8100′] has been saved.

STEP 5: Clone new VM from the snapshot

STEP 6: Log to the appliance and add hostname of the VBR server on /etc/hots

STEP 7: Deploy and configure a new Nutanix backup proxy from the VBR console by connect to exiting Proxy.

This allows you to successglluy integrqtion betwene VBR Server V10 and  AHV appliance:
