I did not think that ceph should be aware of any "external" proxy being used - it runs on one of ceph nodes - I assumed such a proxy would only be relevant to users/clients looking at ceph via web-browser. As far a ceph goes I did: -> $ ceph config set mgr mgr/dashboard/standby_behaviour "redirect" # set it back to default -> $ ceph config set mgr mgr/dashboard/standby_behaviour "error" -> $ ceph config set mgr mgr/dashboard/redirect_resolve_ip_addr true  # resolve to hostnames -> $ ceph config set mgr mgr/dashboard/ssl false -> $ ceph mgr services {     "dashboard": "http://10.1.1.63:8080/",     "prometheus": "http://10.1.1.63:9283/" } Rest is Nginx's, what I'd call a "standard" proxy configuration. If needed - I should spam it here? thanks, L.
