rsync with s3 bucket BadRequestException: 400 AuthorizationHeaderMalformed

Good morning all,

I used to rsync data between one of my buckets in GCS in an S3 one.
This morning I tried to run the same command as always but doesn't work anymore.

This is the error I receiving now:
`Caught non-retryable exception while listing s3://M-S3-BUCKET/: BadRequestException: 400 AuthorizationHeaderMalformed`
And this one:
`CommandException: Caught non-retryable exception - aborting rsync`

This task for us it's really important, how can I fix it?

thanks so much for your time.

With all the best,
Fabio Rigato
