The deal route names a port other than 443. The signed liveness challenge that proves a route, and every later check of a proved route, dials 443 only. Serve the route on 443 (an explicit :443 in the URL is fine) and send PUT /v1/account/route again. Nothing was sent to the route and nothing was stored.
