Description of your issue, suggested solution and other information

The console usage of QPython throw the same SSL: CERTIFICATE_VERIFY_FAILED error except that --no-check-certificate fix it. In the script, it seems this parameter isn't checked.
Is this an issue or is the parameter in the script version different ?
(First, I was using 'parameter':'' for flags then I noticed that verbose was only working with 'True' but it didn't fix the issue.)

Options are spelled incorrectly. Read.

If anyone else wonders what was misspelled, this is what worked for me:

ydl_opts = {
	    'nocheckcertificate': True,
	    'prefer-insecure': True,
	    'verbose': True
	    }
