s3fs_check_service: invalid credentials - result of checking service

Question

I am using s3fs for mounting wrt to s3 bucket

My S3 bucket is AES256 Encrypted

The mount command is

s3fs -o dbglevel=info -o allow_other  -o use_sse=1 -o use_cache=/tmp bucketname /s3mnt 

Doing so I don't get any error message, but the mount is not happening

/var/log/messages

has these error

s3fs.cpp:s3fs_check_service(3765): invalid credentials - result of checking service

Any help?

If you're thinking that you're going nuts after having the right policies and credentials: They ARE probably correct! But is your bucket in a region other than the default us-east-1?

Because if it is, your credentials get lost in redirects...

Looks like we loose auth data following redirects. Adding url param like -o url="https://s3-eu-west-1.amazonaws.com" fixes the problem.
