    My scheduled backups from Windows Server 2016 to Backblaze B2 stopped working. I looked at the logs, and there are frequent similar errors:

    I tried checking the options in Cloudberry for the B2 storage, and when I click on the dropdown for "Bucket name" I get a popup error saying "The request was aborted: Could not create SSL/TLS secure channel". I tried creating a new application key in Backblaze and copying it over, but I still get the same error. How can I resolve this problem?

    Please try updating .Net on that computer to the latest version 4.5 version.

    Can you verify your backup version?

    Unfortunately, that version is very old and no longer supported. Please consider upgrading to a supported version. If you have to use this old version, then check your TLS versions installed and which protocols are enabled. I think you may need to have TLS 1.1 enabled. If you have a maintenance contract, you can reach out to Support for guidance on upgrading or solving the issue. I do not see anything in the system for this error other than a .Net upgrade need (which you checked) or TLS related issues.
