Grafana

Hello everyone,

I just upgraded my environment to 5.2.2, for the upgrade I did use the DB dump from the 4.2 version. No dashboard loads after the upgrade.

Having most likely the same thing, after some time got “504 Gateway Time-out”

UPD: Started working for couple of minutes and now not loading again.

What does grafana server log tell you?
