For all V-Ray and Vantage users out there - there is an important update for the Chaos license server: due to an expiring security certificate, older versions of the Chaos license server will not work properly after January 28th 2025.
The latest versions of the installers on our website are already updated with a newer version of the license server; you can also update the license server manually. More information is available here: https://support.chaos.com/hc/en-us/articles/30185867975185-IMPORTANT-Update-your-Chaos-License-Server-Version
Apologies for the inconvenience!
