Hive HACS losing connection

I’ve been using the HACS Hive integration for about 8 weeks now and it’s worked really well. In the last 2 days the integration is repeatedly reporting that all the Hive devices are unavailable. The HIVE app reports everything connected so it seems it’s an issue with HA or the integration.
Reloading integration doesn’t help.
Restarting HA restores the connection. I haven’t figured out what triggers the disconnection yet.
Anyone encountered this issue before?
I’m thinking of connection directly to the Hive devices and excluding the Hive Hub if this continues, just worried that control may be more difficult.
