I have been having the same problem for about an hour now. Any YouTube video I click on in any player will buffer just fine, the pages will load nearly instantly but the video will never play. I get no error message. I have cleared out all my history, all the cookies and anything that was cached but the videos still won't load. I have HTML5 enabled for YouTube. I have tried going to chrome
/flags and disabling hardware-accelerated video decode but that still did nothing. I've tried other browsers along with incognito mode but nothing has worked. My internet connection is fine, my phone will stream HD video from WiFi and the other computers will load YouTube videos without any problems. Please help!
-Edit- My flash player is automatically updated with Chrome.
-Edit 2- Netflix will not play videos either but, just like YouTube, will still buffer. Again, this is only happening on one computer.
