Although I did search the list for prior posting regarding the issue I had, I finally came across a thread which addressed this issue. In short, updating Ceph to 18.2.2 resolved this issue. The first issue was - as I initially suspected, caused by mgr to perform a verification on the SSL certs presented to it. Once I disabled that using ceph dashboard set-rgw-api-ssl-verify false I was presented with another error, which was then resolved by the Ceph upgrade: Mär 25 10:47:25 bceph01 conmon[260644]: ValueError: invalid literal for int() with base 10: '9443 ssl_certificate=config://rgw/cert/rgw.rgw.JVM.GH79' _______________________________________________ ceph-users mailing list -- ceph-users@xxxxxxx To unsubscribe send an email to ceph-users-leave@xxxxxxx
