Apologies to be bumping this old thread, but I'm having the same issue as the original poster. Unfortunately, after enabling TLS 1.2 and disabling TLS 1.0 and 1.1 in the registry of my WHS 2011 server, my real-time backup job to Amazon S3 (standard, not Glacier) continually fails, and there doesn't seem to be TLS-specific settings in either Cloudberry or on the Amazon side of things. I've been meaning to do a new server build, but I'ld love to stretch out the useful lifespan of my current one just a bit more - but I need Cloudberry working to do so. Can anyone help?
