# MGS9014: share listener unavailable

The server answered `503 service unavailable` to a share request because it
could not open the LAN listener the other device connects to.

```text
[MGS9014] share: no up, non-loopback, private-range IPv4 interface found;
connect to a LAN or Wi-Fi network and try again
  see: .../MGS9014.md
```

## Why

A share serves the console on this machine's private LAN address, never on a
public one. With no private-range IPv4 interface up there is no address a
nearby device could reach, and a listener that cannot bind has nothing to
serve on.

## Resolution

Connect to a LAN or Wi-Fi network and start the share again. If one is
connected, the message names the address the listener could not bind; free
that port or retry once whatever holds it exits.
