Upload cannot proceed. Amazon S3 returned an error message: 0 :: Akeeba\Engine\Postproc\Connector\S3v4\Connector::uploadMultipart():  OpenSSL SSL_connect: SSL_ERROR_ZERO_RETURN in connection to s3-eu-west-1.amazonaws.com:443 Debug info:

Post-processing interrupted -- no more files will be transferred
I have triple checked my settings. Access Key, Secret Key, Bucket name, and Region
I have several sites where I have upgraded Akeeba backup to the latest version, all using Amazon S3 as Post-processing engine, but this is the only site that don't work.
Thanks in advice.
