Proxy error from 127.0.0.1:6443

[derritter88]

Hello there,

not sure if this is an intended behaviour or a bug.
Deployed Flux today on my self hosted Gitlab server via

flux bootstrap gitlab   --deploy-token-auth   --hostname=gitlab.domain.tld   --owner=myself   --repository=kubernetes   --branch=main   --path=cluster/default   --personal

So far this worked out of the box and Flux is doing its job.
But as soon as I want to open a proxied site via Ranchers service tab I get a 502 Bad Gateway exception - e.g.:

{
  "kind": "Status",
  "apiVersion": "v1",
  "metadata": {},
  "status": "Failure",
  "message": "error trying to reach service: proxy error from 127.0.0.1:6443 while dialing 10.42.4.91:9090, code 502: 502 Bad Gateway",
  "reason": "ServiceUnavailable",
  "code": 503
}

At all other namespaces the proxy works flawless - only for flux-system it doesn't.
