Unable to install Veeam CDP Plugin

Products

• VMware vCenter Server

Issue/Introduction

When attempting to install the Veeam CDP plugin, the Veeam server receives 'The operation is not allowed in the current state.' error.  Additionally, Veeam CDP replication may not be working.

 

When checking the vCenter EAM log (/var/log/vmware/eam/eam.log), you see the following error message:

 

 2025-05-01T19:23:35.298Z | ERROR | vlsi | LocalizationFilter.java | 96 | API ERROR: The VibServices vmodl facade.packageContent[opId=#########, sessionId=########]. Fault:

   faultCause = com.vmware.vim.binding.vmodl.MethodFault: "com.vmware.eam.EamIOException: Failed to get input stream of http://<veeamserver.domain.com>:33035/dapi/bundle/8.0.0/12.3.8" caused by "com.vmware.eam.EamIOException: Unexpected status code 503 from http://<veeamserver.domain.com>:33035/dapi/bundle/8.0.0/12.3.8 ",
   faultMessage = null

Environment

vCenter Server

Veeam Continuous Data Protection (CDP)

Cause

This indicates a security device is refusing download of the plugin from the Veeam server.  To confirm, run the following command:

 

curl -kvvv http://<veeamserver.domain.com>:33035/dapi/bundle/8.0.0/12.3.8

 

If you receive the following message, you have a security device blocking the download:

...

<div class="response">

Resolution

Correct the security device configuration to allow the download.
