After today’s update OSMC began to disconnect after a few minutes of video viewing. This happens with files from the internet and local files
Can you count on to help you solve the problem?
Suggest you try with a clean install without installing the unoffical addons first to check if local files are playing fine. If that already gives you crashes then I suggest to check your network. If that setup plays fine than you know that the issue comes from one of the addons.
