We were able to checkout the license from the server system successfully until last week. Suddenly we are getting the attached error msg. Using PowerShell we verified that the port work. Please help to understand what is wring here.



i also get the error:Warning (292006): Can't contact license server "4444@" -- this server will be ignored.

Welcome to INTEL forum. This message is basically because of connection error. Could you kindly help check you license setup again. Starting with your OS support, whether your machine is supported or not (OS) by referring to link below:        


Make sure the port used by license server or vendor daemon is not blocked. The port number is required for Windows systems and should be outside of the 27000-28000 range and be unique on the machine. The following example shows how to specify port numbers in a floating license file. example, specify ports 1800, 1801, and 1802.


SERVER myServer 0123456789ab 1800

VENDOR alterad ./alterad port=1801

VENDOR mgcld ./mgcld port=1802


My suggestion would be:


1)     After VPN connection is established, setup license path in Quartus II>>tools>>license setup.

2)     Verify license server is running by using “lmutil lmstat –a –c <port>@<server> in BOTH server and client machine.

3)     Ping license server via VPN or telnet <host>< port> to check the TCP connection is established


Please stop and restart the server. You need to allow the firewall access to the port number from both server and client machine.


You can also refer to link below for more detailed instructions for Setting up a floating network license server (page 37 of 59):         


You can also refer this following YouTube for license setup.      


You can also refer to this following YouTube on Setting up and debugging Quartus floating licenses.      

Let me know if this information is helpful.
