Hi to all! After upgrading my cluster from squid to tentacle (now on 20.2.1) I'm getting the following error when I try to access any 'page' in the Object section of the Ceph Dashboard: Error connecting to Object Gateway: RGW REST API failed request with status code 403 (b'{"Code":"SignatureDoesNotMatch","Message":"","RequestId":"tx0000000b5bf42356' b'85174-006a0d95b0-308299-eros","HostId":"308299-zone-default"}') I'm pretty sure that in Squid it was working (I don't usually access the Dashboard, but I did after the upgrade to check if everything is ok). The error 'SignatureDoesNotMatch' leads me to believe that there is a problem somewhere with the SSL certificates. But I put RGW_API_SSL_VERIFY to false... I have a SSL certificate (issued by harica.gr) which has different SANs including the hostname of all the nodes where RGW daemon is running (plus a cluster hostname and a wildcard hostname). I used this certificate for the ingress service and for the rgw daemons. Everything is done with a spec file using ceph orchestrator. I'm using the fullchain for the certificates and the the rgw/ingress services are running without any problem Or I'm completely wrong and the problem itself is with the access permissions (error code 403)? Any ideas? Thanks Iztok -- Iztok Gregori ICT Systems and Services Elettra - Sincrotrone Trieste S.C.p.A.
