OnCall was not able to load the current user

[kevingarman]

What went wrong?

What happened:
--I have an existing Grafana install on docker that is sitting behind an nginx reverse proxy
--I've installed OnCall using the "hobby" docker compose file
--In Grafana, I've set the "Oncall backend url" to "http://engine:8080" and it connects ("Connected to OnCall (v1.8.12, OpenSource)")
--In Oncall docker compose file, I have "GRAFANA_API_URL: http://grafana:3000"
--Grafana and Oncall engine containers can ping each other by name
--When I go to any of the Oncall config pages (in grafana), such as "Alerts & IRM --> OnCall --> Settings," I get, "OnCall was not able to load the current user. Try refreshing the page"

What did you expect to happen:
--I would expect the settings page to load
--I'm guessing it's a reverse proxy issue, but it also seems like the oncall engine is ignoring the configured GRAFANA_API_URL

I was able to get around this by disabling the enforce_domain = true in the grafana.ini
