Looks like your certificates for Let’s Encrypt are out of date.

Depending on your OS there must be a solution if you search for one: [let's encrypt urlopen error [SSL: CERTIFICATE\_VERIFY\_FAILED] certificate verify failed: unable to get local issuer certificate (\_ssl.c:1108)\> at DuckDuckGo](https://duckduckgo.com/?q=let%27s+encrypt+urlopen+error+%5BSSL%3A+CERTIFICATE_VERIFY_FAILED%5D+certificate+verify+failed%3A+unable+to+get+local+issuer+certificate+(_ssl.c%3A1108)%3E)

You’ll get the same issue with many apps in fact.

Just had the same issue on Mac OS X Monterey (12.5) with Python installed via the official installer (instead of pyenv or brew). The solution was to run the following from the terminal:
