Error downloading YouTube video using youtube-dl When downloading a YouTube video using youtube-dl, I get the following error:

MacBook-Pro:ytd user$ youtube-dl "https://youtu.be/dgxpBpa9A48"  
[youtube] dgxpBpa9A48: Downloading webpage  
ERROR: Unable to download webpage: &lt;urlopen error [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: unable to get local issuer certificate (_ssl.c:1045)&gt; (caused by URLError(SSLCertVerificationError(1, '[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: unable to get local issuer certificate (_ssl.c:1045)')))


What is causing this? How do I overcome it and download the video?
For some reason youtube-dl has cert issues. I have always found a solution by using --no-check-certificate argument.

From the man page:

--no-check-certificate
              Suppress HTTPS certificate validation


Should really say "Ignores HTTPS certificate validation"...
