Thanks for your support, Using tcpdump and wireshark, I can see both boto3 and PHP transactions have this field: Host: hn.ss.bfcplatform.vn\r\n Which does not contain 8084, so I'm still confused about how it appeared =) But anyway, this configuration in nginx was solved the problem: proxy_set_header X-Forwarded-Port 443; _______________________________________________ ceph-users mailing list -- ceph-users@xxxxxxx To unsubscribe send an email to ceph-users-leave@xxxxxxx
