[SketchUP LMS] player.vimeo.com refused to connect


When i try to use SketchUP LMS to take course, all video cant be played, that condition show notification “player.vimeo.com refused to connect.” in that video

and then, when i try to click next course with navigation link, show pop up error message an AJAX HTTP error, HTTP result code: 200, statusText: parsererror, and another information text error

i hope this error can be fixed as soon as posible, so sketchUP certificate can be taken,
