I just installed it, on an n900 updated to Pr1.1, connecting to Nagios 3.0.6 over https. I entered the configuration and credentials, but I only get "fetching data, please wait..". Never actually manages to fetch the data. Rebooting did not fix the problem either. Could be a certificate issue? we have a self-signed certificate. Maybe I have to ok the cerificate somehow (EDIT: the certificate is already set to be trusted in the built-in browser)
