Failed to bind to port 1900: "Protocol not available". DLNA will be unavailable

[Zeuaireus]

Good Morning,

I have installed Jellyfin on my Qnap today and i haven't been able to connect to it through DLNA. This install is a fresh install using the latest version: [10.8.9-1] on Qnap Firmware: 4.3.4.2242

I have followed all the necessary steps and setup a folder with a single video file, including setting up transcoding. The server is only for LAN users. Now, i have looked through the log files and i have found this error appearing multiple times.

[ERR] [19] Emby.Dlna.Main.DlnaEntryPoint: Failed to bind to port 1900: "Protocol not available". DLNA will be unavailable.

I have Serviio installed on this NAS and there is no issues connecting to it through DLNA. I also know Serviio isn't causing this issue since i have disabled it completely, restarted the NAS multiple times while testing connectivity and Jellyfin still doesn't show up.

VLC is able to see Serviio when both Jellyfin and Serviio are enabled.

I am including the log file from the Jellyfin install in this ticket.

Same problem. Could this maybe be SO_REUSEADDR?
