First, see the status:

ceph mgr services

Then restart it:

ceph mgr module disable dashboard
ceph mgr module enable dashboard

And check again:

ceph mgr services

It take some seconds to restart. You'll see:

avmlp-osm-001 /home/ceph # ceph mgr services
{
    "dashboard": "https://avmlp-osm-002.ciberterminal.net:8443/"
}
avmlp-osm-001 /home/ceph # ceph mgr module disable dashboard
avmlp-osm-001 /home/ceph # ceph mgr module enable dashboard
avmlp-osm-001 /home/ceph # ceph mgr services
