If the issue is only present with a stream via Kodi, and not via any other app (Netflix et al), then it's almost certainly related to either the addon, or the stream source.
If this is illegally streamed content.... that's kind of the price of entry IMO (and we cannot assist there).
If it's just the interface, for an account you sign into and access via Kodi (NHL, HBO, Netflix, Youtube etc can all be accessed inside Kodi), the issue may sit with the addon itself.
If that's the case, reach out to the addon developer (found in 'settings' or 'configuration' for any given addon).
If it's an official addon, your chances of a fix are fairly high.
If it's an unofficial addon, I wouldn't be holding my breath.
