Description of my issue:
Here's the error message we get:
****
Warnings
Upload cannot proceed. Amazon S3 returned an error message: 0 ::
Akeeba\Engine\Postproc\Connector\S3v4\Connector::uploadMultipart(): [55] SSL write: error -5961 Debug info:
Failed to process file /home/creat/public_html/administrator/components/com_akeeba/backup/creat.creathost.com-rhea-20160104-121826.jpa
Post-processing interrupted -- no more files will be transferred
*****
The log file indicates that multipart upload to S3 starts successfully, but then fails after a few chunks are transferred.
We have verified that the root certs are updated on the server, and additionally the root certificate file within the akeeba installation appears to be working properly, and seems to contain the proper Baltimore root cert.
We had one successful backup 1/3 after trying for hours, but none before or since. Also, if we try the button "transfer archive (amazon S3)", it appears to work, but sends no file or at most, only one of the archive, and does not display any errors.
We have numerous instances of Akeeba 4.5.1 backing up to S3 with total success. We have been very pleased with Akeeba for years. We have just moved this site, www.creat.com, to a new server with the same host as previous, with the same configuration private server.
Sorry to trouble you, but we've spent h ours and can't figure it out.
Thank you for great software we rely on.
