Amazon S3 Connection Error

Hello, I have an issue with the connection to Amazon S3, both with the new nodes and the legacy ones. The problem has been occurring for a month. The proxy does not show any errors, and neither does the antivirus. I’m not sure what to investigate.

Thanks for help

Giorgio

Here is the error:
