Unable to update whitelist

I'm running Hoobs in with PiHole and I'm not sure if you're aware, but there is a slightly different configuration for Pihole while running hobbs... I'm new to Pi's and such so I'm just getting my feet wet...

I however attempted to run `sudo python3 whitelist.py` and the output that I'm getting is the following...

This script will download and add domains from the repo to whitelist.
All the domains in this list are safe to add and does not contain any tracking or adserving domains.

[i] Pi-hole path exists
[i] Write access to /etc/pihole verified
[X] URL Error: [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: unable to get local issuer certificate (_ssl.c:1056) whilst fetching https://raw.githubusercontent.com/anudeepND/whitelist/master/domains/whitelist.txt

I know that there may be some issue with the certs after a Hoobs & Pihole install but I'm not 100% sure how to resolve.

Any advise would be wonderful.
