Eufycam 2 is not streaming at HomeKit when outside own WiFi

My 3 Eufycams 2 work great after having bugfixes/updates over the past months. BUT there is one major issue now … I can not view my cams streaming from outside my own WiFi network. I get the messages, I see the recordings, just not the stream of all cams. Removed and added, restarted all devices and everything a few times … nothing seems to work.
I have 3 cams2, Homebase 2, iPads/iPhones and an ASUS RT-AX92U router. Everything works fine in the Eufy app, just not this small but important part within HomeKit
Help me out here guys … I have all my devices in HomeKit and really would like that to be the main thing for everything.
