It seems that in Germany, the update to OS 6 has caused the Fire TV to not allow a proper VPN connection in apps, because my server is located elsewhere and is accessible via VPN. Plexpass and Remote Access work perfectly. With the new Fire TV Stick 4K Max running Fire OS 7, it works again on the same network; only Fire OS 6 is acting up. How can I fix this?
And also it works via mobile phone and via the webbrowser. It works on the cube via amazon webbrowser but via plex app it doenst and it is the same like the fire os 7 4k max stick.
