Due to the migration from the VMware domain to Broadcom's, the URL to deploy packages from the Tanzu Standard package repository which is displayed in the documentation is incorrect and leads to an I/O timeout. The URL currently displayed is:
extensions.aws-usw2.tmc.cloud.vmware.comUtilize the new URL within Broadcom's domain:
extensions.stacks.whitesand.tmc.tanzu.broadcom.com
