I would appreciate some help with my Homey Pro 2019. For a while my Homey couldn’t find and upgrade firmware. Tried factory reset and now I can’t setup up my Homey because it cant upgrade. Some error message saying “hostname/ip doesn’t match certificate’s altnames: Host: firmware.athom.com. is not in the cert’s altnames: DNS:*.campaign.adobe.com”
Problem solved, but I’m not sure how. First I did a reset on my router and set it up again. Secondly I disabled mobile data on my cellphone. Now Homey setup could get on with updating firmware and it works as it should.
