Error [-15.570.0] A valid license could not be obtained by the network license manager
Please verify the following:
- Your license server is running.
- Your firewall is not blocking TCP/IP ports your license server service is running on (the default ports are 27000-27009 and 2080).
- You can also set up FLEXLM_TIMEOUT environment variable.
- You may also need to install IPv6 supporting Network License Manager tools, you can download it from here. Please check this post, Do I need IPv6 Network License Manager for Windows?
Tip: You can use Internet Explorer or Firefox to check if the ports used for licensing are open
