 // HCIDOCS-365 - This issue should be fixed soon, in a 4.16.z release
 * Do not update firmware for the `BareMetalHosts` (BMH) resource by editing the `HostFirmwareComponents` resource. Otherwise, the BMH remains in the `Preparing` state and executes the firmware update repeatedly. There is no workaround. (link:https://issues.redhat.com/browse/OCPBUGS-35559[*OCPBUGS-35559*])
 
+// HCIDOCS-371
+* Deploying an installer-provisioned cluster on bare metal fails when a proxy is used. A service in the bootstrap virtual machine cannot access IP address `0.0.0.0` through the proxy because of a regression bug. As a workaround, add `0.0.0.0` to the `noProxy` list. See xref:../installing/installing_bare_metal_ipi/ipi-install-installation-workflow.adoc#ipi-install-setting-proxy-settings-within-install-config_ipi-install-installation-workflow[Setting proxy settings] for details.

 * When installing a cluster on {aws-first} in a VPC that contains multiple CIDR blocks, if the machine network is configured to use a non-default CIDR block in the `install-config.yaml` file, the installation fails. (link:https://issues.redhat.com/browse/OCPBUGS-35054[*OCPBUGS-35054*])
 
 * When a {product-title} {product-version} cluster is installed or configured as a postinstallation activity on a single VIOS host with virtual SCSI storage on {ibm-power-name} with multipath configured, the CoreOS nodes with multipath enabled fail to boot. This behavior is expected as only one path is available to the node. (link:https://issues.redhat.com/browse/OCPBUGS-32290[*OCPBUGS-32290*]).
