Step 5/7: Requesting sponsor signature
Could not reach the Groundwire sponsor (HTTPConnectionPool(host='143.198.70.9', port=8081): Max retries exceeded with url: /apps/sponsor-signer/sign (Caused by NewConnectionError("HTTPConnection(host='143.198.70.9', port=8081): Failed to establish a new connection: [Errno 61] Connection refused"))).
This is usually temporary — the sponsor may be restarting
or the network may be briefly unavailable.
To retry, re-run with your master ticket:
./gw-onboard --master-ticket '[ticket]'

Both TCP and ICMP fail, so the sponsor host itself appears unreachable, not just the signer port.
