LE automatic update broken

Update is part of the libreelec settings add-on, and judging by the bump in users for the latest version that takes place when we enable a release for auto-update the system generally works fine - but you may run into some local issues. Our userbase keeps getting larger and we've noticed the response times for the JSON file that provides available files info are getting slower and sometimes this times out - and my guess (without debug log evidence we can only guess) that the request fails and thus update isn't triggered. There are also some traffic management controls in-place on the update server that you could run into if there are many LE devices in your network, but that's also unlikely. Kodi debug log (as the settings addon runs under Kodi) would be a starting point.
