[SSL: CERTIFICATE_VERIFY_FAILED]

Since 2021-09-30, the day of the Let's Encrypt DST Root CA X3 expiration, pydio-sync stopped working with:

00:57:40 ERROR   140401309402880 Thread-3 [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:590)

SSLError: [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:590)
00:57:40 ERROR   140401317795584 Thread-1 [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:590)

This is because a very old list of CA certificates (especially with the now expired root certificate DST Root CA X3 and without the now valid "ISRG Root X1") is included.

We need to update the list of certificates from here, I believe: https://github.com/certifi/python-certifi/blob/master/certifi/cacert.pem

Since there seem to be no new releases, any idea how to create a new build?
