Against a real ACME server the proxy orders, the challenge is answered
at the name on port 80 through the proxy itself, the authorisation goes
valid, finalisation is accepted, and the authority issues a certificate.
The client then posts to an empty URL to collect it, and never does.
Read from the authority's own log rather than inferred. Across one run
it issued two certificates and accepted finalise three times: the client
reaches issuance every attempt and fails at the same step after it.
Ruled out and recorded, so nobody repeats it: the directory is complete;
the authority's API certificate covers the address; the challenge path
works. A hand-written server config was suspected and was wrong —
replacing it with the server's own default, changing only the challenge
port, gives the identical error.
Filed rather than pursued because what remains is interop between two
libraries against a server that exists to be a test server, and may say
nothing about a real authority. What the mesh needed to show, it showed:
a routed name gets a certificate ordered from a configured authority,
and an unrouted one gets nothing — that second assertion passes.
Phase 1 closes with this one item partly open. Two of its four tasks
needed no code at all, the network shape was built, and the next thing
to learn comes from moving a module rather than a fourth lab run.
