Agent stops scraping at scrape_interval=60s

Grafana Prometheus
1

We’re experiencing some issues with our grafana agent (prometheus) scraping configuration. If we set the scrape_interval to 15s or 30s, everything is working fine but once we increase it to 60s it stops scraping our kubernetes-pods job from the configuration below. Is there anything additional we need to change in the configuration to make 60s work? We initially deployed the agent when the 15s scrape interval was still the default setting.
