Plex hadn&#x27;t worked for me when I tried it out of curiosity some years ago. Some devices worked, some had failed to discover it at all. IIRC, the network was fine and it seemed like some issue with their DLNA&#x2F;SSDP implementation but I haven&#x27;t bothered to debug proprietary software. Installed MediaTomb and it worked reliably nearly out-of-the-box.
