No edge found

What you see: the Mesh pane says No edge proxy found and Sharing is off; the mesh and disk-sharing switches are greyed with "Needs an edge proxy in reach."; an apply was refused with "no edge proxy is reachable from this box"; the public name of the box stops answering.

What the box looks for​

Every 20 seconds the box looks for an edge in two places: an announcement on the local network (for a company edge on the same LAN) and the configured address (for the LosOS edge or a company edge elsewhere). An edge counts once its /health answers. The Mesh pane shows every edge it found, with a sign saying whether it proved itself official, or the sentence under No edge proxy found says what was tried:

The pane saysMeaning
"This box searched its network and asked <address>; nothing answered."Both roads were tried. The address is the configured one.
"This box searched its network and nothing answered."No address is configured; only the local network was searched.
"This box could not search its network, and nothing answered elsewhere."The box's mDNS service was not running, so a LAN edge could not be found even if present. A reboot brings it back.

From the LAN​

  1. Does the box have the internet? An edge on the internet needs it; a company edge on the LAN does not. The Overview says whether the box is answering; the box has no "internet" light, so try the edge's address in your own browser from the same network. If only the local network works, that page is Only the local network works.
  2. Is the address right? Settings → Advanced, find losos.proxy.registrarUrl. It is the base address of the edge's API, https://losos-edge.dasmat.us for the LosOS edge's control plane. A company edge on the LAN announces its own, usually http://<edge>.local:8443.
  3. Company edge on the LAN: same network segment? mDNS announcements do not cross routers or VLANs. Enter the edge's address instead of relying on discovery.
  4. Is the edge announcing itself? A company edge is found on the LAN only with losos.edge.lan.advertise on; without it, boxes need its address. Whoever runs the edge sets that.
  5. Is this box enrolled? An edge only accepts boxes on its allow-list, each with a token. Discovery does not need enrolment, the tunnel does: a box that was reinstalled has a new identity and must be enrolled again by whoever runs the edge.
  6. Was the edge reinstalled? The box pins the edge's tunnel key on first contact. A rebuilt edge with a new key is refused, on purpose; the operator clears the pinned key on the box (a file under the box's secrets, reachable only via a rebuild) or re-enrols the box.

The box reconnects on its own​

Once the edge answers again, the next scan finds it, within 20 seconds, and the Mesh pane follows a few seconds later; the tunnel comes back without a restart. Nothing you turned on is turned off by an outage; only turning on is refused while no edge is found, and that is Sharing is refused.
