V-Ray Could Not Obtain License
Here you can find the list of symptoms and their likely cause when V-Ray could not obtain the license. Please check the resolution part at the end of this section.
Symptoms:
When you try to render with V-Ray Standalone, an error message appears in the console: “Could not obtain a license (10061).”
Cause:
No access to the Chaos license server.
Symptoms:
When you try to render with V-Ray Standalone, an error message appears in the console: “Could not obtain a license (-98).”
Cause:
No available license on the Chaos license server.
Symptoms:
When you start the V-Ray GPU render server, there are no error messages in the V-Ray console, but when a job is sent to the V-Ray GPU render server there is an error in the console "Could not obtain a license (10061)."
Cause:
No access to the Chaos license server.
Symptoms:
When you start the V-Ray GPU render server, there are no error messages in the V-Ray console, but when a job is sent to the V-Ray GPU render server, the error in the console is "Could not obtain a license (-98)."
Cause:
No available license on the Chaos license server.
Resolution:
Please go through the check-list below.
1. Checking the Chaos license server:
Start the Chaos license server from Windows Start menu > All Programs > Chaos > Start Chaos license server.
You may receive a message warning that the Chaos license server is already running.
Open the link http:// localhost :30304 in a web browser on the same machine.
This will open the Chaos 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 Chaos license server is working, you need to check the available licenses. On the same machine, where the Chaos license server is running, open the link http://localhost:30304/getstatus
Please refer to Chaos License Server Status section in the Chaos License space for more information on the type of licenses you need to look for.
3. Checking the connection to the license server:
If V-Ray is on the same machine as the Chaos 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 Chaos license server. If you get a web page like the one below, V-Ray can access the Chaos 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 Chaos 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 > 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 V-Ray Standalone.
Note: If the Chaos 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.
Missing Chaos License Server Icon
Symptoms:
The Chaos licensing server is running but there is no icon in the Windows System Tray.
Cause:
The icon is hidden by the Auto-hide unused icons option of the Windows System Tray or the Chaos license server is registered as a Windows service.
Resolution:
If you have the Auto-hide unused icons option of the Windows System Tray, click on the double-arrow icon to expand the full list of icons.
If you still do not see the Chaos licensing service icon, that means that the V-Ray licensing service is started as a Windows service and in that case it cannot show any graphical user interface. There is currently no resolution for this; you need to manage the Chaos license service from the Windows Control Panel > Administrative tools > Services applet.
V-Ray GPU is Crashing
Symptoms:
When rendering with V-Ray GPU on CUDA, it crashes without showing a specific error message.
Cause:
The scene you are trying to render is too large and the Graphics card memory is insufficient.
Resolution:
You can try to reduce the scene size by reducing the polygon count or by using lower resolution textures. V-Ray GPU has an option called Resize textures for GPU that you can use to automatically resize textures during rendering on the GPU.
Alternately you can upgrade your graphics device with one containing more memory.

Cause:
No available license on the Chaos license server.
Resolution:
Please go through the check-list below:
Start the Chaos license server
Open the link http:// 127.0.0.1 :30304 in a web browser on the same machine.
This will open the Chaos 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 Chaos license server is working, you need to check the available licenses. On the same machine, where the Chaos license server is running, open the link.
http://127.0.0.1:30304/getstatus
3. Checking the connection to the license server:
If V-Ray is on the same machine as the Chaos 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 Chaos license server. If you get a web page like the one below, V-Ray can access the Chaos license server from this machine. In the example screenshot below the IP address of the machine with the license server is 10.0.2.89
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 Chaos 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 that the license server settings are correct. In the Terminal run the following:
/Applications/Chaos/V-Ray/Standalone_for_bigsur_univ/VRay.app/Contents/MacOS/setvrlservice.bin -dump
This will show you the IP address or the name of the computer that V-Ray is trying to connect to; If it's incorrect refer to the Manually Change the License Server IP page.
