Article Applicability

This article is specifically regarding the Veeam Backup & Replication console failing to connect after the Veeam Backup Server's hostname has been changed.

The error shown in the Cause section of this article may occur due to other reasons, which are documented in KB2127.

Challenge

After changing the hostname of the Veeam Backup Server, the Veeam Backup & Replication Console fails to connect, displaying the error:
Failed to connect to the Veeam Backup & Replication server:
No connection could be made because the target machine actively refused it <IP>:9392

When this occurs, the Veeam Backup Service will be stopped and cannot be started. The diagnostic logging on the Veeam Backup Server will contain the following messages, which show that the server is attempting to connect to the previous hostname.

%programdata%\Veeam\Backup\Svc.VeeamBackup.log:

Info [DB] Connecting to SQL Server (CurrentUser=[NT AUTHORITY\SYSTEM], ServerInstance=[<OldHostname>\<SQLInstanceName>], Options=[Direct])
Info [DB|ERROR] Failed to connect to server

Solution

To correct this issue, update the Veeam Backup & Replication configuration with the current hostname by following these steps:

  1. Open the Configuration Database Connection Settings program, which should appear in the start menu of the Veeam Backup & Replication server.
  2. Within this program, select Veeam Backup and Replication, then click next.
    (If Enterprise Manager is not installed, you will not be prompted to select a product.)
  3. Adjust the value specified in the Server name field to match the correct hostname.
  4. Click Next, and Veeam will connect to the database. Wait for this process to complete.

  1. Click Next, and the Veeam service will be started. When this has been completed, click Finish, then try accessing the Veeam Backup & Replication console.

More information

  • If you have any problems following these steps, please contact Veeam Support.
  • Troubleshooting for issues opening the console when the hostname has not changed are available in KB2127.
  • Hostname changes of other devices, such as hypervisors, repositories, or proxies, require additional steps covered in KB1905.
