Jaksta FAQ:"URL is not supported" when downloading from YouTube Modified on: 2023-04-28 01:02:51 -0400

Could be that you have expired Google certificates on your machine.  Google Internet Authority G2 certificate seems to be a common one that recently expired on users machines and is causing this problem.

Debug log will show:  

ERROR: Unable to download webpage: <urlopen error [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:590)> (caused by URLError(SSLError(1, u'[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:590)'),))

To check for expired certificates:

1. Open the certificate manager - certmgr.msc  (Start > Run)

2. Action > Find Certificates.

3. In the Contains field type 'google' (without quotes), and change Look in Field to "Issued To"

4. Delete any expired certificates.
