https://addons.libreelec.tv appears to be down for several hours. Tried from machines in Germany, Switzerland, the US and Australia, all with the same result:
$ curl 'https://addons.libreelec.tv/11.0.0/ARMv8/arm/addons.xml.gz.sha256'
curl: (7) Failed to connect to addons.libreelec.tv port 443 after 292 ms: Connection refused...and it's up again. Thanks!
The server is back and I was able to install from the libreelec repository 
Also worked for me this morning on the systems that wouldn't.
Everything is working here aswell.
I cannot install any unknown repos for the raspberry pi 5 with the 11.0.4 release. Only raspberry pi 4 works. I did try the nightly build 11 it does not work at all and nightly build 12 still buggy!
I am unable to connect to the LE repo last 2 days
IPTV Add-ons repository is installed, but the add-ons are not available. LibreELEC 10.0.4 RPi 3B+ IP XX202.106
There are no errors from the IPTV add-ons repo. So as told already in the other thread: If it reports no add-ons, you need to discuss that with the people who created that repo (which is not LE and not Team Kodi, so not our problem to solve).
I seem to get addon updates; except for youtube addon. It was stuck on 7.0.2.2.
But as I was getting a lot of errors I had to update manually. Installed the latest 7.0.3.2 form https://github.com/anxdpanic/plugin.video.youtube/releases. Looks a little different, but works great.
Now I am a little confused, because the yt-addon does no longer show up as installed. Do I have to update manually for ever? The repository still only lists 7.0.2.2 for yt?
If you follow the Kodi forum support thread and read some of the GitHub issue tickets; some rework is needed (and being done) and when that's completed an update will be pushed through Kodi repos. Until then manual updates are needed.
