Description of your issue, suggested solution and other information

I updated to the latest version of youtube-dl today and noticed that youtube videos are hit and miss now using the script with most of the times leading to failure to download videos. I've attached the verbose logs above of one of the videos I tried to download. When entering the command in the command prompt it hangs for a few seconds before spitting out the error message.
