DLNA not working since docker upgrade to 4.10.0.40

[BlumCoLe 1]

Hey,

cannot use emby DLNA anymore ...my tv (Hisense) shows the server under "sources" but after that, it doesn't load the directory list and throws me back to the sources list of my network devices.

Restart/reinstallation of plugin Dlna 1.5.6 didn't help.

Log:
