SENSE appears to be blocking Hive in the UK
The Hive hub connections appear to be blocked by SENSE. The hub is showing as disconnected but if I replace the router then it all works fine.
The hub does a connection to AWS on 443 and keeps it alive afaics.
Would love to give you more info but SENSE doesn't appear to allow to view any useful log information to diagnose.
This happened recently with one of the firmware upgrades since it all used to work fine.
