Iframe with username and password in reverseproxy

Hi all,

I’m trying to pass username & Password in URL with apache2 as reverse proxy, we can say it even using the same URL in IFRAME. But i can’t to access the plugins. it throws error like instantiating, screenshot is enclosed for reference.

I’m using simplejson as datasource, due to which i’m unable to obtain a dashboard.

I’m using grafana version 5.0.4.
