Description of your issue, suggested solution and other information

I keep getting this error since yesterday. Other than this, not sure why but sometimes when youtube-dl fetches the download URL of a video and goes to sleep, it sleeps for a lot more than the mentioned number of seconds, it feels as if its stuck and just sits for half an hour or more.

@dstftw why has my issue been closed? the duplicate that you connected this bug report to, seems unrelated to mine. I have seen other ppl's issues like mine and they were simple enough to figure out for you.
Please can you tell me what's similar between by bug and the duplicate link that you have marked here.
I don't see anything wrong with my command line.
