Hi Ramon! Your machine is trying to access to video, but somehow it is blocked or delayed in doing so. This could be because of multiple things, but according to the actions you've tried, it is most likely a network timeout. We're looking here at our dashboard and we see the error. Another thing might be a session timeout occurred. Do you allow cookies to be stored on your machine? This is unfortunate, let me know if this keeps on happening. Best, Arie

Hello Arie, I tried to clean the browser and this video and the next one still has problems. In the "How to design a bridge" the same happens with the third video, the second and fourth stop in a point and don't continue. (others are working perfectly) The message that appears is attached. Thanks Ramon

Hi Ramon! We recently switched video player, could you try to clear your browser cache: https://www.google.com/search?q=clear+browser+cache and see if it runs? Also is it only this video or all of them? Let me know and thanks for reporting this. Arie
