I recently embedded a game from NewGrounds on this webpage: https://mikey670.github.io/wdd130-MK/muketronics/mrstretch.html. The game is 'Mr. Stretch and the Stolen Fortune' and I am the owner of this game. At first the game was running properly, but now when the page is loaded, the iframe is grey and has the error: uploads.ungrounded.net refused to connect. The iframe was just copied from the game page.
