That's quite strange, but it isn't a problem with the Youtube plugin - your CoreELEC box is having network issues.

The log indicates that cURL timed out trying to open the video stream URL. The Youtube plugin only provides this URL to Kodi for playback, and the URL works fine (I can open the URL in your log without any issues).

You could try a few different things to see if it helps:

• Enable MPEG-DASH in the Youtube plugin settings
• Disable HTTP2 in Kodi advanced settings https://kodi.wiki/view/Advancedsettings.xml#network

all other video playback perfectly fine, so its not only a network problem, at least imo, otherwise i would expect other videos to fail too. i will try your recommendations and see what happens

This is not necessarily the case. Not only do different videos use different servers, but there are a number of reasons why connections to certains servers may not work properly. As an example I recently had an issue with my ISP where incorrect BGP routing resulted in routes to specific servers, in a specific geographic location, hopping back and forth around the world, resulting in high pings, timeouts, and packet loss.

That being said, I suspect your issue is a very specific issue, because I have the same device as you, also running CoreELEC, and something very similar happened to me.

It only happens in certain instances, when using libcurl on certain platforms, with certain servers that support HTTP2. For some as yet unknown reason, when connections to those servers are closed, libcurl sometimes tries to reuse a closed connection rather than open a new connection. There is more discussion about the issue here: xbmc/xbmc#17047

If it is this issue, then the two suggestions I made will probably help. If not, then unfortunately I don't really have anything useful to add - your device is trying to connect to a working URL, but something specific to your network or internet connection causes it to timeout when trying to do so.

You can also try to get a proper debug log following the instructions here: https://kodi.wiki/view/Log_file/Easy
Enable Verbose logging for the libcURL library in the component logging settings: https://kodi.wiki/view/Log_file/Easy#Enable_component-specific_logging
