Hi vtverdohleb,
Thank you very much for this add-on. I am not quite sure if I am posting at right place. Sorry to unearth this topic, but I cannot find answers to my issue.
I have installed package: DNS-327L Mediatomb Package v2.00_03032014_UA from your link
on a DNS-327L FW DLINK_DNS327L.1.07b06(3.13.0422.2016)
Everything was fine for around 10 days until last night. I was really happy about this media server, accessing my video and music from my Freebox Revolution through UPnP. I watch a last episode of a serie last night and then went to bed. However, coming back home tonight the UPnP server is not listed on the Feebox Server any more. I opened the DNS-327L web interface and it takes for ever before it can display "My Favorite Applications". Anyway, I click on the "MediaTomb" icon and tried to launch the interface but I got an error message: "Firefox can’t establish a connection to the server at 192.168.0.XX:9002".
I restarted the DNS-327L through the web interface. And still nothing. When I go to the "Add-on Center", MediaTomb is not listed as if it was not installed.

I tryed to re-install it and I got the warning message, clicked OK and then a message saying that the installation failed.
MediaTomb still appears on "MyFavorite Application" but not in "Applications". Nothing seems to happen when I click or double-click on the icon anymore.
I can access "http://192.168.0.XX/Mediatomb/index.html" but the page takes for ever to finish loading. If I press Esc, I can click on "Launch interface" but then I get the Firefox port 9002 error again.
Have you come accross such issue before?
