predefined reports are not working

[philipp.a.kolb]

Hello community hopefully I'll find help.

I installed icinga core, classic ui, idoutils, report and jasperreportserver via the quickstart dokus on the icinga website. Everything works fine I also added some host into my icinga master. 

I can connect to my JasperReportServer (tomcat) and can login. Under /root/icinga/datasource is the predefined ido datasource where I can test the Connection. It is working.

But if I test a report under /root/icinga/reports/hosts and select one I can't select any hosts. There are none given. 

Where is the Problem? I can see hosts in my classic web gui of icinga e.g. localhost and one remotehost and everything is green.

thanks in advance

kind regards
