If you are here reading this troubleshooting guide "new Veeam Backup server but then Veeam won’t start", this means you must have recently installed Veeam Backup and Replication Server or must have recently upgared it. As you can see from the images below, these are some errors I encountered while installing Veeam Backup and Replication in my lab enviornment. Because I do not want to create a dedicated article for each problem as they are similar, I decided to group them as shown below. Here is an article on how to install and configure Veeam Backup and Replication 11 Community Edition.

Note: The following errors in itself do not make sense "Failed to start service / connect to Veeam" and "connection refused". This is not a connection or firewall issue as well. Please continue reading to learn how I resolved these issue. To fix this, you may want to review the Veeam logs and the event viewer for more information".

Veeam Service Startup Error and Registry Keys

Because of this error, you will also notice that most Veeam services are not running. Also, the SQL Server Express was stopped at this moment. Therefore, the error “Remoting Channel Sink UriNotPublished. RequestUri is ‘/VeeamService’ simply means the Veeam Service has not started yet“. To fix these issues, ensure the following registry keys have your server name and the SQL instance and Veeam database name are correct in the windows registry. If everything is fine here just as it is in my case, please proceed to the steps below. Below are the registry keys that need to be verified.

HKEY_LOCAL_MACHINE\SOFTWARE\Veeam\Veeam Backup and Replication\SqlInstanceName
HKEY_LOCAL_MACHINE\SOFTWARE\Veeam\Veeam Backup and Replication\SqlServerName
HKLM\SOFTWARE\Veeam\Veeam Backup Catalog\CatalogSharedFolderPath

Also, try to ensure the Veeam Backup and Replication services and the database services are running. If you get an error as shown below while trying to start any of the services, please proceed to the recommended solution below.
