Hello Eric,
You are probably hitting the git commits listed on this thread:
http://lists.ceph.com/pipermail/ceph-users-ceph.com/2017-April/017731.html
If this is the same behaviour, your options are:
a) set all fqn inside the array of hostnames of your zonegroup(s)
or
b) remove 'rgw dns nam
When I send the a RGW request with hostname (with port that is not 80), I
am seeing "SignatureDoesNotMatch" error.
GET / HTTP/1.1
Host: cephrgw0002s2mdw1.sendgrid.net:50680
User-Agent: Minio (linux; amd64) minio-go/2.0.4 mc/2017-04-03T18:35:01Z
