Hello, 

Our site is no longer able to push backups to S3. I receive the following error: 

 /home/mercuryproonefir/public_html/administrator/components/com_akeeba/backup/site-mercurypro.onefirefly.com-20220303-140824utc-f6MVSJbONE85TH6a.jpa Error received from the post-processing engine: Upload cannot proceed. Amazon S3 returned an error. Akeeba\Engine\Postproc\Connector\S3v4\Connector::uploadMultipart(): [35] OpenSSL SSL_connect: SSL_ERROR_ZERO_RETURN in connection to mercurypro.s3.dualstack.us-east-1.amazonaws.com:443 Debug info: Post-processing interrupted -- no more files will be transferred

Our host has ensured us that OpenSSL is up to date.

Any ideas on what could be causing it?

The error message comes from the PHP cURL extension and indicates a problem between your host and Amazon. It says that cURL cannot perform the SSL handshake with Amazon's server.

If it only happens sporadically this is a random network issue, you can't do anything about it.

If it happens on every backup, including backups you run manually form the backend of the site, it would mean that your server has a broken IPv6 stack, it is blocking the connection or it has a transparent proxy which blocks the connection. You should contact your host about that.
