Spinnaker Applications screen will not load: check the Gate endpoint

TL;DR

Check the browser console for failed requests to the gate endpoint applications path. With a custom URL, set override-base-url for both Deck and Gate so CORS between them works; without it the browser rejects Deck requests to Gate.

Steps

1. Check the browser console for failed requests to the gate endpoint applications path. If you access Spinnaker on YOUR_HOST:9000, forward Gate port 8084 to your machine. With a custom URL, set override-base-url for both Deck and Gate so CORS between them works; without it the browser rejects Deck requests to Gate. On a local install, also confirm Redis is running at the configured address and restart Spinnaker after starting it.

Why this happens

The original report does not dig into a root cause. It documents the symptom and the fix that resolved it.

Source: Official Spinnaker Setup FAQ: after installing, the Applications screen shows Error fetching applications or spins forever. The documented root cause is that the browser cannot reach the Gate API endpoint, which breaks the Deck UI.
