| Clusters configured with OpenID Connect (OIDC) at the Kubernetes layer encounter issues when authenticating with the [non-admin Kubeconfig file](../clusters/cluster-management/kubeconfig.md#cluster-admin). Kubeconfig files using OIDC to authenticate will not work if the SSL certificate is set at the OIDC provider level. | Use the admin Kubeconfig file to authenticate with the cluster, as it does not use OIDC to authenticate. | June 21, 2024 | Clusters |
| During the platform upgrade from Palette 4.3 to 4.4, Virtual Clusters may encounter a scenario where the pod `palette-controller-manager` is not upgraded to the newer version of Palette. The virtual cluster will continue to be operational, and this does not impact its functionality. | Refer to the [Controller Manager Pod Not Upgraded](../troubleshooting/palette-dev-engine.md#scenario---controller-manager-pod-not-upgraded) troubleshooting guide. | June 15, 2024 | Virtual Clusters |
| The VerteX enterprise cluster is unable to complete backup operations. | No workaround is available. | June 15, 2024 | VerteX |
| Edge hosts with FIPS-compliant RHEL Operating System (OS) distribution may encounter the error where the `systemd-resolved.service` service enters the **failed** state. This prevents the nameserver from being configured, which will result in cluster deployment failure. | Refer to [TroubleShooting](../troubleshooting/edge.md#scenario---systemd-resolvedservice-enters-failed-state) for a workaround. | June 15, 2024 | Edge |
| The GKE cluster's Kubernetes pods are failing to start because the Kubernetes patch version is unavailable. This is encountered during pod restarts or node scaling operations. | Deploy a new cluster and use a GKE cluster profile that does not contain a Kubernetes pack layer with a patch version. Migrate the workloads from the existing cluster to the new cluster. This is a breaking change introduced in Palette 4.4.0 | June 15, 2024 | Packs, Clusters |
| An issue prevents RKE2 and Palette eXtended Kubernetes (PXK) on version 1.29.4 from operating correctly with Canonical MAAS. | A temporary workaround is using a version lower than 1.29.4 when using MAAS. | June 15, 2024 | Packs, Clusters |
| [MicroK8s](../integrations/microk8s.md) does not support multi-node control plane clusters. The upgrade strategy, `InPlaceUpgrade`, is the only option available for use. | No workaround is available. | June 15, 2024 | Packs |
| Clusters using [MicroK8s](../integrations/microk8s.md) as the Kubernetes distribution, the control plane node fails to upgrade when using the `InPlaceUpgrade` strategy for sequential upgrades, such as upgrading from version 1.25.x to version 1.26.x and then to version 1.27.x. | Refer to the [Control Plane Node Fails to Upgrade in Sequential MicroK8s Upgrades](../troubleshooting/pack-issues.md) troubleshooting guide for resolution steps. | June 15, 2024 | Packs |
| Azure IaaS clusters are having issues with deployed load balancers and ingress deployments when using Kubernetes versions 1.29.0 and 1.29.4. Incoming connections time out as a result due to a lack of network path inside the cluster. Azure AKS clusters are not impacted. | Use a Kubernetes version lower than 1.29.0 | June 12, 2024 | Clusters |
| OIDC integration with Virtual Clusters is not functional. All other operations related to Virtual Clusters are operational. | No workaround is available. | Jun 11, 2024 | Virtual Clusters |
| The VerteX enterprise cluster is unable to complete backup operations. | No workaround is available. | June 6, 2024 | VerteX |
