Situation
When adding repositories to a downstream cluster under Apps > Repositories in the Rancher UI, they appear in a Downloading state with an error that says Get "https://<chart_URL>/index.yaml": net/http: TLS handshake timeout
Other behavior which may be seen as a result of this is performance problems when browsing the Apps > Charts section and charts in that section not loading.

HTTP_PROXY
