WARNING - socket closed
What does this mean?

After this warning this happens...
`WARNING - socket closed

Error - Error retrieving info from hub : Error: connect EHOSTUNREACH xxx.xxx.xxx.xxx:8088-(445)`

The hub and the remote works just fine even with this message. Only homebridge is affected and I don't know why.

After this the connection is gone and restart the service does not work. I have to disconnect the Hub to get it work again.
