The controller logs "annotation group ConfigurationSnippet contains risky
annotation" and a rejected annotation group drops the entire ingress from
nginx.conf. comfyui.riotpiao.com therefore answered 404 for every request with no
line in the access log, which is why the host looked routed but served nothing.
ingress-nginx sets the Upgrade and Connection headers itself for a websocket
upgrade, so the snippet was never needed.
