I set up an Azure Managed Grafana instance in Azure. It generated a custom URL for me. Let's say it's:
https://grafana-fzaeb1evc4d7cyaf.eus.grafana.azure.com (this is not the actual URL).
I also have a domain: domain.com.
I created a CNAME DNS record for dashboard.domain.com that points to grafana-fzaeb1evc4d7cyaf.eus.grafana.azure.com
It worked, but I'm getting a 404 from nginx. I'm guessing there's a configuration setting somewhere in Azure or Grafana to tell it to respond to my dashboard.domain.com URL, but I can't find it in either system and some Googling has yielded nothing.
Any thoughts on how I can get this to work?
Setting custom domain names for Azure managed instances of Grafana is not supported yet.
The best what you can do right now is to set redirect from short name to default one.
