Not able to add Graphite as Data source in Grafana

Hi Everyone,

I have installed Grafana 10.2.6 and Graphite 1.3.14 on a Virtual Machine using Oracle Linux 9. I am going to use them with Icinga2 for the purpose of system monitoring.

Now using the Grafana web interface I am trying to add a Graphite Data Source but I receive an error “The requested URL was not found on this server”

The configuration is:

When I press “Save and test” I get the following error:

In grafana.log and /var/log/mesages I see the following error:
logger=context userId=1 orgId=1 uname=admin t=2025-03-05T15:17:31.002322204+02:00 level=info msg=“Request Completed” method=POST path=/api/datasources/proxy/uid/aaa6f284-5ad6-4a12-b390-db33d543405d/render status=404 remote_addr=127.0.0.1 time_ms=2 duration=2.385204ms size=196 referer=http://localhost:3000/connections/datasources/edit/aaa6f284-5ad6-4a12-b390-db33d543405d handler=/api/datasources/proxy/uid/:uid/*

I am having hard time trying to figure out what I have done wrong, can someone help with any idea?

Thanks.
