This is an evaluation installation.

Tried selecting “Demo” package first. UI install spun for hours.

Unpackaged zip file again and selected “Standard” package next.

events.log states: Extension ‘package-standard’ has been installed.

Error (in userdata/openhab.log) repeats every 60 seconds.

Do you have a host based firewall? Perhaps it is blocking OH’s ability to reach out to the internet to download the bindings. I think it downloads it from Cloudbees.

This was a good tip. Thanks!

I had a custom firewall configured.

I temporarily disabled it and believe I have safely arrived at first base.
