DFence on no IFRAME on mobile

Good evening, first ... sorry for my bad english. Little time ago since last write english words 😉

So my problem is. My channel is private and I made some Plugins --> Chart With Multiple Series. That works perfect.
On my ESP8266 runs a server and provides me the charts. I included them as an iframe like this.

Sorry, I didn´t get the code in here. I put it on pastebin. --> LINK

When I log on the site with my computer 192.168.178.200 it works perfect.
When I log on the site with my mobile this massage comes.

"The author made this visualization private."

All devices (computer/mobile/ESP8266) are in the same WiFi !

Any ideas ???

Thanks for help !
