Could not obtain a license (0).

[tmcthree]

Hi,

So, Vray worked for about a week, then seemingly spontaneously, it stopped working and gave me the error

Could not obtain a license (0).

Nothing seems to have changed since it was working. The dongle device seems to be working properly in the device manager. The floating license server seems to be running. But it won't render in Maya.

I've tried reinstalling the license and Vray itself. But it makes no difference.

Any help?

Thanks in advance.

It seams like a firewall issue , please verify that Vray License Server is allowed through the firewall.
For a quick test please turn the firewall off temporary and run one test rendering.
If that doesn't help please contact us at support@chaosgroup.com and include a link to this thread.
