That's a bit worrying. I guess it means that it's not broadcasting as shared
- which would fit with the error message.

One thing you could try - set up keychain authentication with keys. I've only
used it in an ssh situation, but I believe it can work in lots of others. You
give the keychain password at the start of a session and that is checked
against known-hosts on the remote machine. That's certainly worth a try.
