Be sure to call youtube-dl with the --verbose flag and include its complete output in this post. The output should start with something along the lines of [debug] System config: []. Most likely, you'll find that you are using an outdated version of youtube-dl (if not, please actually include the complete output with --verbose).

Make sure you are using the latest version. This error looks a lot like #3232, which has been fixed in recent versions.

You seem to have installed youtube-dl with a package manager or pip. Use the tool you used to install youtube-dl to update youtube-dl.
