Cannot obtain license from the dongle

...

When using dongles with License Server version 5.0 or later, make sure that the following requirements are met:

• The License Server is installed and running. See the Installing the License Server page for more details.
• WIBUKEY drivers need to be installed on the machine, where the License Server is running.
• The dongle needs to be plugged in the machine where the License Server is running.
• The DONGLE option of the License Server needs to be enabled. See the Dongle usage page for more details.

When the setup is correct, the HOME page of the License Server's interface will display information about the licenses stored on the dongle.

1. Restart the machine with the V-Ray license server and dongle installed.
2. Unplug the dongle and plug it into a different USB port, preferably a USB 2.0 port. Make sure that Windows properly recognizes the dongle and doesn't show an error message. If you receive an error message, please see The V-Ray license server can't find the dongle under Dongle Issues . 
3. 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 might receive a message warning that the V-Ray license server is already running.
4. 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.

...

If the status page does not look like the screenshot above, 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 the application's access to the network or blocking the communication on TCP/IP port 30304. Please contact your system administrator for more information.

I can't access my dongle licenses from another machine

...

When using a dongle license connected to the License Server you are only able to access the dongle licenses on the machine that the dongle is connected to or from another machine within your local network. You are unable to access dongle licenses over the internet on another machine logged into the License Server outside of your local network. 

How to solve "No license available" error

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.
