Reconnection

When the tunnel loses the connection, it continues to run. It waits 5 to 10 seconds and connects again. After each failed attempt, the wait time increases, up to 2 minutes.

The server and the tunnel each send a check every 15 seconds. After four checks with no answer, the sender closes the connection. The tunnel then connects again.

A terminal that uses the tunnel closes when the connection is lost. The page shows Connection lost and a Reconnect button. See Troubleshooting.

If a tunnel does not connect, the reason is one of these.
