I’ve Grafana v6.7.3 and Loki v1.4.1 running in the same cluster. The promtail (1.4.0) is running on the separate application cluster. In Grafana, I sporadically get “Loki: Cannot connect to Loki. 502” error when I click the “Save and Test” button. Additionally, I also get the logging dashboard (12019) return a “Template Init” error sporadically when I try accessing it. It can’t be a Grafana to Loki communication issue as both sit in the same cluster. Has anyone else run into this issue?
