A join needs matching label names. Try using label_replace <https://prometheus.io/docs/prometheus/latest/querying/functions/#label_replace> on one side, e.g.
haproxy_server_http_responses_total * on(exported_namespace, route) label_replace(openshift_route_info, "exported_namespace", "$1", "namespace", "(.+)") Once that's working, then you can add group_left(...) or group_right(...) as required.
