Q: Youtube continuously reloading webpage

On certain videos i'll go to watch a video and it will reload the webpage saying "a problem occurred with the webpage so it was reloaded" and have a pop up with a bunch of stuff i don't understand it will do this 3 times before going to a gray screen that says a problem repeatedly occurred with the website id below it. I'm using safari and i'm using OS X Yosemite 10.10.5 anyone have a clue whats causing this? Thanks.
