• Yep, connecting straight to the Pi hosted version on port 1888. The console logs show everything working as you'd expect - lots of Initialising lines, and no errors. Connects websockets to the Pi without issue.

    I thought for a moment I'd identified something - there was a complaint about parsing JSON from the config - but there was junk in the local storage. Clearing that out got rid of that error but still no luck getting connected. I also connected to the Pi through a Chrome incognito window to make sure that there was nothing else knocking around that could've had an impact (I once had issues with the LastPass extension on another web-based IDE - that caught me out) but there was no difference.

    Checked mosquitto is running correctly - it is, and NodeRED can publish and subscribe quite happily to it. Everything looks like it should be working, but no dice :(
