Cloudron v6.2.4 - Nginx Access-Control-Allow-Origin Policy blocks Grafana to access Prometheus
-
@brutalbirdie CORS headers are set by the app, it shouldn't be platform related. So, if Grafana cannot access prometheus, it's because prometheus needs some CORS setting.

My problem with that is, both Grafana and Prometheus did not get updated for 2 weeks on thev6.2.4
instance.
Grafana 7.4.3
andPrometheus Server 2.25.0
They did not change but the version of Cloudron got upgraded fromv6.1.2
=>v6.2.4
that's the only thing that changed. -
@brutalbirdie Nothing has changed in the reverse proxy configs other than referrer-policy. So, I am surprised that it worked before. I can only think of some app update causing a problem.
-
@brutalbirdie I haven't tried this yet. Do you know if this setup requires basic auth to work in the apps?
-
@brutalbirdie yes, that is most likely the issue. Let me try to push a fix.
-
@brutalbirdie I have enabled it in package v1.4.1 . Can you please try?
