We are excited to announce that we have launched our new Hive Community! HiveNation will remain as an archive, but all new posts, discussions, and articles will be created on Hive Community. You can visit our new community at thehivecommunity.aerohive.com
This means either a) Your initial 30 day demo has expired & you need to enter a valid HiveManager entitlement key or b) Your existing HMOL subscription has expired or c) Your valid Entitlement key may have not been applied to your account yet.
Have you purchased an HMOL subscription for your devices? I would contact your reseller and check the status of your order if so.
