MainUI - Grafana and video problems with remote connection using iOS App via myopenhab.org

… need to get clarity regarding some problems with remote connection using iOS App!

openHAB 3.3.0 stable
iOS app: 2.4.52 (Testflight)

Not sure this is a “Config”, “MainUI” or “iOS App” issue.

Example:

Video stream in Basic UI sitemap:

Video url="http://user:pwd@192.168.0.15:80/video2.mjpg" encoding="mjpeg"

This is working both in local network AND remotely via myopenhab.org

Video stream in MainUI via image card and ipcamera binding, since Video card with mjpeg doesn’t work in MainUI:

http://192.168.0.13:8080/ipcamera/192168015/ipcamera.mjpeg

This is only working in local network BUT NOT remotely via myopenhab.org

Same issue with Grafana using Webframe card in MainUI…

http://192.168.0.13:3000/d-solo/4OdYJNbMk/energie-pv-haus?orgId=1&refresh=1m&theme=light&{period}&panelId=2

This is only working in local network BUT NOT remotely via myopenhab.org

Any idea why this is not working remotely - especially since my first example (Basic UI) works locally and remotely?

Hope someone can advise.

… whereas BasicUI ist working:
