Hi,
Please confirm that your origin IP is 109.9x.1xx.9
?
because if that so , you seems to have a invalid cert on your backend

More details here: https://curl.haxx.se/docs/sslcerts.html
curl failed to verify the legitimacy of the server and therefore could not
establish a secure connection to it. To learn more about this situation and
how to fix it, please visit the web page mentioned above.
Please fix this invalid cert on origin first
