Failed to acquire GRID Virtual Workstation license

I am running a Windows 10 for both server and clients with an Nvidia Tesla T4. Everything works fine launching new VMs when the server is recently launched with a fresh install. We’ve tried several times, and it always fails after a couple of hours running. Once it starts to fail, the logs are always the following:

16:04:43,253 WARN srvpool-966 [16C63EFF4533 request] Unable to handle request for feature GRID-Virtual-PC 2.0 count=1. Reason: FEATURE_NOT_AVAILABLE.
16:04:45,112 INFO srvpool-932 [16C63EFF4533 request] Successfully handled request for feature Quadro-Virtual-DWS 5.0 count=1 correlationID=531fc554-55f5-40d0-adb2-1002d7646549.

16:04:48,432 WARN srvpool-966 [16C63EFF4533 request] Unable to handle request for feature GRID-Virtual-WS-Ext 2.0 count=1. Reason: FEATURE_NOT_AVAILABLE.

The feature usage on the server at the time of the above logs, of course, is the following:

The environment is the following:

  • Citrix 8.2
  • Windows 10 64-bit for both server and clients
  • Latest Nvidia drivers installed (461.33)
  • License server is 2020.05.0.28406365
  • The Java SDK used is OpenJDK 1.8.0_282-1
