ConnectionRefusedError

I get the following error when running docker-compose up:

Start by running docker-compose up and inspect tinychain.py around send_to_peer at line 1034, where node2 cannot connect to node1. Compare the startup timing shown for node1 and node2 and determine whether the reported connection refusal is expected during startup. Done means the compose run no longer reports the peer connection failure.
