Ok
Stepped away from Indigo for a year and came back because Indigo ZWave solid compared to the one I had been testing.
Not sure how but Indigo updated to 2021.1 but ran into issues of not being able to get Control Pages working and suspect the issue may be the reason why Node Red Indigo Node not connecting to Indigo.
Did some research and found that MacOS 12.1 'broke' web server in Indigo 2021.1 and you have to upgrade to 2021.2.
For that I had to pay for a subscription, its Ok I was going to do that anyway.
The Control Pages are now working, still trying to get Node Red working.
But I now get this message on starting Indigo..
So it appears the updated 2021 Indigo
"This app will not work with future versions of macOS and needs to be updated to improve compatibility. Contact the developer for more information."
Apple are declaring a release of Indigo that is 6 weeks old is already obsolete?
I know the guys will get this sorted in time, but if I was a new subscriber I would be deeply troubled by this notice.
