s3-tests failed with CEPH on Raspberry Pi

Hello I am trying to create a testbucket on a Ceph Raspberry Pi cluster(local) and I get the following error message:

OS:Debian Jessie

Does anyone know about the error ?

Solution:
On the gateway node, open the Ceph configuration file in the /etc/ceph/ directory.

Find an RGW client section similar to the example:

[client.rgw.gateway-node1]
host = gateway-node1
keyring = /var/lib/ceph/radosgw/ceph-rgw.gateway-node1/keyring
log file = /var/log/ceph/ceph-rgw-gateway-node1.log
rgw frontends = civetweb port=192.168.178.50:8080 num_threads=100
