Cloudflare has detected that your configuration has enabled our Authenticated Origin Pulls feature. Recently, we renewed the certificate that our edge network presents to your origin due to the upcoming expiration of the current certificate on January 11, 2020.
This was identified on zone(s): domanin1.com domain2.com
To ensure uninterrupted service first verify if the authenticated origin pull certificate is installed on your origin. If it is installed and the expiration of the certificate is January 11, 2020, you need to update your origin server to authenticate with the new authenticated origin pull certificate anytime before January 11, 2020.
You can find the updated certificate and follow the instructions for updating popular origin servers in this Cloudflare Help Center article: https://support.cloudflare.com/hc/en-us/articles/204899617/.
When enabled, this feature adds an extra verification on the SSL handshake to ensure the request comes from Cloudflare.
In order for it to be correctly configured, you previously needed to download an "extra" certificate and install it in your webserver. From that point on your origin will try to validate that requests come from Cloudflare. This certificate is now expiring and needs to be replaced.
Please note that if the feature is enabled and the "extra" certificate was not installed, nothing will happen. If this is the case, no action is needed and you can choose to disable the feature.
Finally, this certificate is installed at your origin webserver - we have no control on this configuration.
If any additional questions should arise, please feel free to contact our Support team by making a ticket at https://support.cloudflare.com/.
Thanks again for choosing Cloudflare!
