A valid license could not be obtained by the network license manager.

Error [-15.570.0]

All thanks, everything works.
Simply there was not a true license.

-15 Cannot connect to license server system.
The server (lmgrd) has not been started yet, or the wrong port@host or license file is
being used, or the TCP/IP port or host name in the license file has been changed.


did you check the license manager to see if it was set up correctly?

you probably need o ask whoever is handling that in your company

Darren is right.  You need to check to make sure the NLM server is running properly and that it is not being blocked by a firewall.  Ports 2080 and 27000 need to be opened.  You can check it from the client with:





Both should give a jargon page in Internet Explorer.  That's how you know the ports are open.

Hello. First, run a “Perform Status Enquiry” in LMTOOLS to make sure licenses are up and running. Next, turn off the firewall on the server to test and see if you can pull a license. If so, put the firewall back on and add exceptions for the ports (previous post).

If you moved your license server from one place to another, your machines could just be looking in the wrong place. You could set a variable to force the path.

1.)           Right-click the My Computer icon.

2.)           Click the Advanced tab.

3.)           Click "Environment Variables".

4.)           Under the System Variables window, click "New".

5.)           In the Variable name field enter ADSKFLEX_LICENSE_FILE

6.)           In the Variable value field enter @YOUR_SERVER_IP_ADDRESS

If you are looking in the correct location for a license, and there are licenses displaying in LMTOOLS, you are likely blocked by the firewall on the Server, possibly the workstation as well.

Thank you for taking part in our community!

I'm having the same issue but the instructions below did not seem to resolve our issue. 


Our version of LMTOOLS is running on a Win-08 R2 server and clients are a mixed between Win-7 and XP. 

When I completely disable the server domain firewall, LMTools issues licenses accordingly.  Changing workstation firewall makes no difference so I focused on the domain firewall settings.


Win-2008R2 has an option under firewall settings called "Allow a program or feature throught Windows Firewall".  Under this option, I selected LMTOOLS UTILITY for both tcp & udp.  Now, under 2008 R2 Firewall advanced settings, I see that LMTOOLS UTILITY is set to allow all inbound and outbound request on all ports.   When I re-enable the Windows firewall with the changes mentioned above, the clients return to failing and unable to obtain a license from LMTOOLS-Error-15.570.0. 


I've backed tracked now and simply disabled the Windows domain firewall as a work around.
