Suffering from same issue here, I was using MySQL with id/pw instead of ssl and worked fine until a few days ago the client in a newly installed python environment returned:

sqlalchemy.exc.OperationalError: (MySQLdb.OperationalError) (2026, 'TLS/SSL error: Certificate verification failure: The certificate is NOT trusted.')
(Background on this error at: https://sqlalche.me/e/20/e3q8)

Uninstalling mysqlclient, clearing cache and installing mysqlclient==2.2.4 solved the issue for me (with that MySQLdb.get_client_info() returns 3.3.8).

I tried disabling SSL auth in various methods but I had no luck on mysqlclient==2.2.5. Considering existing users using id/pw might face this issue, disabling ssl auth on default as mysqlclient up to 2.2.4 did might be a better option.
