If you have more than one Acronis Access Gateway server on your network, you will have to allow additional server addresses in the Good Control console. If you do not so this, the Access Mobile Client will only be able to connect to the single server you configured in the previous step.
To permit access to additional Gateway servers, select the Client Connections item in the lefthand menu in the Good Control console.
In the Additional Servers box, enter the Gateway server's DNS name or IP address and it's port, then click the "+" icon to add it to the list. The default Gateway server port is 443.
