Error: “The remote server returned an error: (403) Forbidden” During VRA Installation on Hyper-V Host

Viewed 554 times


This article covers a scenario in which a VRA installation will fail due to the the inability to download from the ZVM VM.

Root Cause

The Hyper-V host on which VRA will be installed fails to download the VRA installation file from the ZVM.

There may be multiple causes that could include proxy settings, anti-virus software, IE download settings in security settings of the ZVM.


VRA installation failed with the following error:

Failed to install Zerto Hyper-V agent at host: <host name> due to error:Host:[Host <host ID> server <Server ID>]failed to download file:https://<ZVM IP>:9669/files//GetFile/zerto.hyperv.agent to local path:c:\ZertoAgent\ZVM\ due to error:The remote server returned an error: (403) Forbidden


Log on to the host and open the following link (found in the error) in Internet Explorer or Edge browser:
  • https://<ZVM IP>:9669/files//GetFile/zerto.hyperv.agent
       Check if the installation file can be downloaded to the host.

Check if the host has proxy settings for accessing the ZVM server:
  • If a proxy setting is defined, disable this and reattempt the VRA installation.
Check if any anti-virus software on the host:
  • If there is anti-virus software installed, disable anti-virus and reattempt the VRA installation.
If no proxy setting is defined and anti-virus software is not installed on the host, proceed to the steps below:
  • Determine the SCVMM Run As account. If the user does not know, this can be determined from ZVM logs.
