I have done the following when I had similar issues;
1. search for Areswizard kodi addon and there's an option, to tweak your settings for buffer free. you can google how to do this.
2. subscribe to real-debrid and google how to configure this in kodi. you won't regret subscribing to real-debrid.

my 2cents.
