Harry, can you please open a tracker issue at https://tracker.ceph.com/projects/dashboard/issues/new with the following details: - "ping" to the standby manager/s IP address. Let's see if they are reachable/routable from your end. - "ceph -s" to see if everything is ok. - "ceph mgr services" to get the URI of the active ceph-mgr - "netstat -anp | grep 8433" (please replace 8433 with the port you're using for Dashboard) in the standby managers to check if they're actually listening to it. - "curl -ki https://<standby-ceph-mgr>:8433" (same, please replace the port). If the curl doesn't work with a hostname, please retry with the corresponding IP address. - Check out the stand-by manager logs for any Error or "Traceback" message. Thanks!
