Tanzu Hub Upgrade Planner Shows "Upgrade Planner is currently unreachable"

Products

• VMware Tanzu Platform Core

Issue/Introduction

When navigating to Fleet Management > Upgrade Plans in Tanzu Hub and clicking Create Upgrade Plan, the page displays the error banner:

Upgrade Planner is currently unreachable. Please try again later

No upgrade plans can be generated, and the Upgrade Plans list remains empty even though foundations are properly attached to Tanzu Hub.

Environment

VMware Tanzu Hub 10.4

Cause

Tanzu Hub's Upgrade Planner requires outbound internet (HTTPS) access to Broadcom/Pivotal-hosted domains to retrieve current product version, EOGS, and compatibility data.

Resolution

1. Confirm Tanzu Hub's proxy settings (tile: Proxy Settings tab, or proxySettings block in the Hub manifest/values) are configured correctly for your network (leave unset only if this foundation has genuine direct internet egress)
2. From the Hub control node, test connectivity to the required domains:

   • curl -v --max-time 10 https://broadcom.com

   • curl -v --max-time 10 https://upgrade-planner-api.pivotal.io

   • If the TCP connection succeeds but the TLS handshake resets, engage your network/security team to add explicit SNI/hostname-based allow rules (not just IP-based rules) for: upgrade-planner.pivotal.io and *.pivotal.io
