Comment:

 The WebSocket bridge has a certificate cache:
 https://gitweb.torproject.org/pluggable-
 transports/snowflake.git/tree/server/server.go?id=d865b7c252d3a7efd789a84757fc2635b1964921#n309
 The broker doesn't cache certificates, but it should, to avoid this kind
 of problem.

 In the meantime I can get a conventional cert, but we'll have to add
 `--cert` and `--key` options to the broker like meek-server has:
 https://gitweb.torproject.org/pluggable-transports/meek.git/tree/meek-
 server/meek-server.go?h=0.33#n394
