  1. Checking the V-Ray license server:

    Please restart the machine with the V-Ray license server and dongle installed. Unplug the dongle and plug it again in a different USB port, preferably USB 2.0. Make sure that Windows properly recognizes the dongle and doesn't show an error message. If you receive an error message, please refer to  V-Ray License Server Can't Start in this section.

    Start the V-Ray license server from Windows Start menu > All Programs > Chaos Group > V-Ray License Server for x64 > Launch V-Ray license server

    You may receive a message warning that the V-Ray license server is already running.

    Open the link http://localhost:30304 in a web browser on the same machine.

    This will open the V-Ray license server status web page. If it looks like the screenshot below, the license server is working.


     

  2. Checking the available licenses on the license server:
    After you ensuring the V-Ray license server is working, you need to check the available licenses. On the same machine, where the V-Ray license server is running, open the link http://localhost:30304/getstatus

    Please refer to Change Changing your License Settings page in the Set Up Your V-Ray License section for more information on the type of licenses you need to look for.

    If you do not see the V-Ray 3.0 licenses, this means that your dongle has to be reprogrammed as described in Dongle and Online Licensingusage page in the Set Up Your V-Ray License section.If you don't see free licenses this means that all available licenses are in use and you can't have more concurrent users.
     

  3. Checking the connection to the license server:

    If V-Ray is on the same machine as the V-Ray license server, you can skip this step.

    To make sure that nothing is blocking the connection to the license server on the machine where you want to run V-Ray, open the link http:// <IP_address> :30304 in a web browser, where <IP_address> is the IP address of the machine with the V-Ray license server. If you get a web page like the one below, V-Ray can access the V-Ray license server from this machine. In the example screenshot below the IP address of the machine with the license server is 10.0.0.160

    If you get an error message that the web page can't be accessed then there is a network problem that prevents the connection to the V-Ray license server. If you have any firewall or antivirus software running on your machines make sure they are not blocking applications' access to the network or blocking the communication on TCP/IP port 30304. Please contact your system administrator for more information.
     

  4. Checking the V-Ray license settings:

    On the machine where you want to use V-Ray, run the V-Ray license client configuration utility from Windows Start > All Programs > Chaos Group > V-Ray for Maya 20xx for x64 > Change license settings. In the dialog that appears, make sure that the IP address in the License server field at the Primary license server tab is entered correctly and that the connection port is 30304. If you modify any of these settings, you will need to restart Maya.


    Note: If the V-Ray license server is running on the same machine as V-Ray you can use localhost or 127.0.0.1 in the License server field.
