Issues connecting to Core RPC over Tor

Running on MacOS. Initial connection succeeded. A few days later, the connection failed with these errors:

Seems to be expecting an Electrum (BWT) server, even though I'm trying to connct to Core RPC?

The request does not appear to be getting out the door. Run "test Connection" throws immediately.

Initially, I had to disable my global Tor daemon on 9050 to make this work. Perhaps re-enabling that daemon between usages caused an issue? Doesn't sound likely.

Duplicate of #83. It's unclear how this could ever have succeeded. Let's track in the other issue.
