Description

I am having issues with the youtube site ( I was able to download successfully from other sites), the program appears to be able to get the web page, but fails to download the media files, and times out after a while.
it looks like the problem is in some ssl bits...

I am also having issues with local issued SSL certificates on latest commit

ERROR: Unable to download webpage: <urlopen error [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: unable to get local issuer certificate (_ssl.c:1108)> (caused by URLError(SSLCertVerificationError(1, '[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: unable to get local issuer certificate (_ssl.c:1108)')))

Most likely network issue on your side.
