VLC on FireTV can’t access NAS on AVM Fritz Routers

[SBA]

Hi Team,

I face problems again with VLC connecting to two different Fritz Box Routers (7490 and 7590) attached HDDs, this time on two different FireTV sticks (Full-HD and 4K), all devices running on actual firm- and software. VLC does not show up any files at all but the internal demonstration files of the Fritz Box using upnp, while it does just fine on the same two different setup locations while using VLC on iOS devices. I had nearly similar problems vice versa around a year ago which got fixed after intensive conversation with your team. But that problem was limiting the list to 50 files while it does not show up any on the hdd nor the hdd at all.
It seems as if these problems appeared with the last FireTV update by Amazon since there wasn‘t an update for the AVM Fritzbox since it worked the last time. An older version of VLC behaved similar, no changes after updating to current 3.3.4.
VLC on a FireHD Tablet works also well.

Thanks for your help.

In German:
VLC auf FireTV kann nicht auf zwei Fritzboxen von AVM (7490 und 7590) mit upnp auf die mit der NAS-Funktion angeschlossenen HDDs zugreifen, nur auf die in der Fritzbox abgelegten Demo-Dateien. Gleichzeitig funktioniert der Zugriff von VLC für iOS fehlerfrei. Alle Geräte sind mit aktueller Firm- und Software versehen. Problem scheint mit dem letzten Update von Amazon für die FireTV-Sticks aufgetreten zu sein. Auch eine ältere VLC-Version zeigte das Verhalten. Auf einem FireHD Tablet funktioniert VLC fehlerfrei.

Is there anybody out there who has similar problems or could test it? Since I have these issues on two setups, I wouldn‘t think that I‘m alone with this. And AVM Fritzboxes are most likely the most sold routers at least in Germany. Thanks for help.
