Connection refused?  The device at this address is a Sonos Playbar.  There was a firmware update applied yesterday (5/24), but the playbar has been in use and has been operating normally after the update.  This error occurred what another set of speakers was activated using Alexa.

Things are back to normal with the Node server after a restart.

Looks like the speaker was not available (likely after the firmware update/reboot) and at the same time (during the restart) a connection failed.  I thought I had caught everything around the speaker restarts.  Looks like something is not being caught.
