I have windows 2008R2 server hosting Flexnet. Windows 7 enterprise on clients using matlab 2015b,2014b. Worked fine for weeks until unknown cause of error. All 9 clients same -96,491 license mgr error. All clients can resolve DNS and ping ip. Firewalls were disabled to test with no result. default port 27000 is open and listening according to netstat. All systems rebooted, reinstalled, Virtual server created for flexnet licensing, still get same eror with new Server hosting licenses. Authentication works fine, error comes up when software starts on clients.

It sounds like you might have already read http://www.mathworks.com/matlabcentral/answers/95122-why-do-i-receive-license-manager-error-96 so you are probably going to need to contact Mathworks about this.

So, did you manage to solve this problem? If so, could you please enlighten us? I get the same license error (-96,491) under a Windows 2012R2 server

Thank you for replying! I haven't found any workaround, yet, so I have to contact Mathworks, I guess.
