I tried to debug the issue and added a logging of an image URL to the homeassistant/components/media_player/webostv.py:
@property
def media_image_url(self):
"""Image url of current playing media."""
if self._current_source_id in self._app_list:
_LOGGER.error("'" + self._app_list[self._current_source_id]['largeIcon'] + "'")
return self._app_list[self._current_source_id]['largeIcon']
return NoneLog entries:

There is no such path in my system but looks like there is a reason why it throws the exception: HTTP client cannot resolve a host of the local path. However, I don't know why does it resolve the path which does not exist in a system.
