Grafana simple json datasource referer

Hi Guys
i have a Problem. If i want to use simple json as datasource, my backend/ api is implemented in Django I allways get in django the error no forbidden no referer. I´ve looked up serveral times why doesn’t grafana
send the refer. Therefore I’ve changed the grafana form http to https but in the end it doenst work.
can anybody help me please ?

I suggest enabling debug logging to see if you can get more information about what Grafana is doing (or not doing).
