Continuing the discussion from Hub Update 1.1.5:

updated to 1.1.5 a little earlier now the hub is hung. on trying to go to hub ip this is the status message at bottom of the browser window:

thank you.

My hub was also hung upon arriving home this evening. Unfortunately I don't have any helpful evidence to provide. Latest version.
