Did you try stopping both and then starting them again? That clears up all the state they have.

Directors themselves think they're having trouble connecting to each others.. Annoyingly it doesn't give specific error messages about what happened. I should improve the logging..

If the state clearing doesn't help, maybe this has something to do with the OS or the network is really having some issues.
