I get frequent errors like failed to start socket: [Exception... "Component returned failure code: 0x80004005 (NS_ERROR_FAILURE) [nsIUDPSocket.init]" nsresult: "0x80004005 (NS_ERROR_FAILURE)" location: "JS frame :: resource://gre/modules/SimpleServiceDiscovery.jsm :: _search :: line 159" data: no] in the Browser Console.

Can we disable this service if it fails to open the socket or something?

sure

BTW: In my case the problem was that I use Bittorrent Sync and the SSDP port was in use by it according to: sudo lsof -i :1900 Once I quit Bittorrent Sync, I was able to see a Roku in the Send Video to Device list.

Yea, same here. Presumably Bittorrent isn't opening the socket such that it can be shared.

I think we'd need to set SO_REUSEPORT on the socket to allow multiple listeners on the same port, which is not yet exposed as an option in nsIUDPSocket. Also, I don't think such an option exists on Windows. Of course, it's no help for the root cause of the problem unless BitTorrent also makes a change.

FWIW, I think it's fine to continually try and use the service if the port is in use but the warning should probably be off by default (perhaps behind a debug pref for the module).

Related, probably something to fix at the same time: 02-20 12:36:21.335 W/GeckoConsole( 2899): [JavaScript Error: "failed to convert to byte array: [Exception...
