Lab 3-1 fail for s3 connection problem

Hi, I encountered connection error msg from lab 3-1 task 2 in “s3cmd ls” command, it maybe caused by vm-nic in host-only configuration in admin node, pls advise!

Best Regards,

Hello, what is the output of ceph -s? Is the rados gateway present?
If not, try executing ssh mon3 systemctl status ceph-radosgw@rgw.mon3.service.

Sovled by restart radosgw in mon3, many thanks !
