Nextcloud version (eg, 20.0.5): 28.0.5
Operating system and version (eg, Ubuntu 20.04): Ubuntu 22.04.3
Apache or nginx version (eg, Apache 2.4.25): Apache 2.4.52
PHP version (eg, 7.4): 8.1.2

The issue you are facing:
I have files that are stored on Amazon S3 storage with server side encryption enabled. Files that are older than says 3-4 years cannot be opened. They seem not to be properly decrypted. When downloading them I cannot open them.

Is this the first time you’ve seen this error? (Y/N): N

Steps to replicate it:

The output of your Nextcloud log in Admin > Logging:
