Fix “No connection could be made because the target machine actively refused it”

There are multiple causes for this failure to connect, such as firewall issues etc. In my case, the services weren’t running. To fix this, follow the steps below.

Launch the services.msc to see if the needed services are running. As we can see, the SQL Server Service isn’t running.

To resolve this, click on start or right-click on the service and click “start”.

Also, I noticed the Veeam Backup service and the Veeam Backup Service REST weren’t running as shown below.

I started both services and as you can see below, the two services are running.

Launch the Veeam Backup & Replication Tool and enter your credentials. I am currently connecting with my Windows session authentication. Click on connect when you are ready.

As you can see, Veeam is starting up and we should be able to access the console very shortly.
