Setting up a new C7, and trying to connect Hub Mesh to my C4 to facilitate the transition... I've discovered that Hub Mesh does not connect properly when the HTTPS-only UI option has been enabled at /hub/advanced/certificate
Once this was disabled on both hubs, they connected instantly. Not sure if this is expected behavior based on implementation, but since the option is available I would expect all features to work with it enabled.
I submitted a ticket via email to support@hubitat.com about a month ago, but only got the generic "referred to engineering team" response, and crickets since...
P.S. @bobbyD there's some mixed messaging in these generic responses -- it states To add additional comments, reply to this email.
-- but then a second email states that Our system does not recognize replies to this ticket
