Here is the moode_librespot.log contents from one attempt to activate Spotify Connect, which timed out in ~55 seconds. I can't interpret this well enough to guess whether this indicates a problem with librespot (and should be posted on their GitHub issues, as suggested by @roderickvd), or represents a problem with Mo0de (config or integration). I'd be happy to post any other log content that might be helpful. Many many thanks again for your attention.
