KB ID 0000758 Dtd 04/02/13

Problem

Seen when running Veeam Backup and Replication.

the target machine actively refused it

Error Task Failed Error: No connections could be made because the target machine actively refused it Also when trying to connect to VMware VCenter from the Backup and Replication management console;

Failed to connect to by SOAP, port 443

Error Failed to connect to “Host-name” by SOAP, port 443, user “User-Name”, proxy srv: port:0 Unable to connect to the remote server No connections could be made because the target machine actively refused it {IP-Address}:443

Solution

There are a few things that might cause this, make sure the Veeam Server can “Ping” the VCenter and the hosts. Also make sure if you use a proxy server there is an exception for traffic going to this IP address. In my case the problem was simply that the VMware Server service was not running on the Virtual Center.
