It worked perfectly, after some update (1.9.x), it stopped to lose normally after a pause. As soon as the pause lasts more than 4 minutes, that's all. The video has to be launched. Without pausing, it works great.
Rollback to the previous version does not help. Apparently somewhere in the settings the problem, although it has not changed the settings for 5 months, just the server itself was updated.
