I have a user that is getting "A license file is required to enable compilation of your design for the family of devices."

[LChi1]

When they were here at our location, they were able to connect to get license. When they returned to their location, they can't. Adding server to the host file did not help.​ Any ideas?

Hello,

Welcome to INTEL forum. This could probably a connection or VPN prob. 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.
