License not releasing when VDI logs off

Was doing some performance testing, and noticed our vGPU backed Horizon desktops weren’t going above 15 fps. After some digging, I found that our Horizon VMs aren’t releasing licenses to the server. It appears that the license expiry time is 2 months for some reason. Not sure how to change this, or get the licenses to release.

Just got off the phone with NVIDIA. Turned out I had a ‘bad’ version of the licensing server. Uninstalled that version, installed the latest, and all appears to be well.
