Description of your issue, suggested solution and other information

I am sure you know about this one already. I experienced this issue months ago and upgrading along with pafy resolved it. However the problem has returned, and I am using the latest version of youtube-dl according to your Github and Pypi repo.

As already pointed out you're using an outdated version.

I am using the latest version of youtube-dl

You must prove that with single complete verbose log.

[rootVIII]

Is that not the log I provided above???
[debug] youtube-dl version 2019.02.08

I'll just save us both the trouble and stop using the module

Again: you must provide the complete log of run that fails, not two logs from different runs. 99% that you are using different versions from console and from where it fails. Bother to read issue template already.
