How to fix the annoying YouTube 400 error

Just click to open the vertical ellipsis or more options icon to the top far right of Chrome’s browser and scroll down and select “Settings.” Scroll to the bottom of this screen and select “Advanced.” In the Privacy and Security section below and towards the end select “Content Settings.” The next thing to do is to select “Cookies.” After you select Cookies a new screen will appear and on this screen click and open “See All cookies and site data.” At the top right you’ll see a line with a magnifying glass and in the blank space it will say Search cookies. In this space type youtube and just below will appear a button that will say “Remove All Shown.” Click this button to remove all shown and another button will appear that will ask if you want to continue, select the button “Clear All.”

Now you can close the settings tab and open YouTube and watch what you wish without the annoying 400 error.
