Problem with prometheus broker metrics
We've noticed there are no prometheus metrics from the snowflake broker showing in grafana for the last 15 hours: https://grafana2.torproject.org/d/a9G61S_Mk/snowflake-broker-metrics?orgId=1&from=now-24h&to=now
The snowflake broker exporter is working fine: https://snowflake-broker.torproject.net/prometheus
So maybe this is a prometheus issue?
