Review the list of known issues on the 31.xx release.
AKS clusters with an underscore "_" in the resource group name are detected as vanilla Kubernetes clusters instead of AKS clusters in the host scan results.
The Prisma scanner may potentially fail to retrieve image details for Docker registries and may fail with 429 connection error when you try to scan more than one Docker registry at a time.
To avoid this error, set the REGISTRY_SCANNERS value to 1 in the twistlock.cfg config file.
Fixed in 31.01.123
Fixed an error in deploying and upgrading the Host Defenders on Windows Server 2019 installed on AWS.
