I included the grafana app in my my web-site by using iframe,like this simplified version below:
iframe src ="http://192.168.5.39:3000/dashboard/db/Stromzaehler?orgId=1&from=now%2Fd&to=now%2Fd&panelId=1&width=800&tz=UTC%2B02%3A00" width='100%' height='900'
This works perfect on Win7/Win10 Platform with both Firefox and Chrome. If no cookies are set, i will be redirected to the login panel, set my credentials and voila’ I am in!!!
However on Iphone or Ipad; After entering credentials the login Panel is simply reloaded asking me again for credetials… - forever…
Webserver: Apache (on Host-A)
Grafana Vers. 4.6.1 (commit: cac8b97) (on Host-B) - fresh install
both hosts are on my local (private NW)
