S3 trouble: storage configuration

What am I doing wrong here?

Since I can’t post a second image the error is ‘invalid parameter: 1 validation error found’ but doesn’t specify what that error is.

Endpoint should be just s3.us-west-1.amazonaws.com without the s3:// prefix.

I get the same error with or without the s3:// prefix

Looks like there was a dash ‘-’ missing in region. Ouch.

us-west-1

not

us-west1

but now it looks like I can’t finish the next step of adding the storage. The ‘Add’ button is greyed out if I choose a password. If I don’t, I can ‘Add’ but I want encryption.
