Trust failure on Minio-S3 after Upgrade to

After upgrading from connections to a Minio S3-compatible can be validated in the destination panel. It also changes the type on every save from “Minio SDK” to “Amazon AWS SDK” after clicking “check connection” or saving the configuration.
As it looks, the jobs are executed without errors, but clicking on “check connection” creates the error “Trust failure”.
After a job has run successfully or is running the error on “check connection” does not appear.
Looks like old connection data is used in the “check” but not in the backup process itself.
