Well this happens every day and to make the sync work again I need to restart Kodi. Otherwise it will not track what has been watched.
Are you the author of the add-on? Why wouldn't the addon reconnect when the connection has broken? lets say give up after 3 unsuccessful reconnect retries..

Well, this is not a dedicated design decision, but seems to present an error that did not come up when testing the mySQL feature. I added an issue on GitHub. Can you be more specific? Does this happen in the mode "watch user changes", or after performing a full update of the whole database in the periodic mode?

Sorry for my late response, haven't stopped by for some time.

I have enabled "watch user changes", this is error occurs soon after finishing watching a movie or a episode, when the addon tries to update the watched status of the movie/episode.
