I haven't seen the `any:5984` notation before. It should be `0.0.0.0:5984` to work across devices. AFAIR, even Windows supports that these days.

Start with the Fauxton Verify Installation flow in a Docker CouchDB 3.3.2 setup and reproduce the replication test failure. Trace where the request to http://any:5984/verifytestdb/ is created or resolved, then verify the installation steps complete without the resolution error across the reported Docker/OSX environment.
