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():  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?
