No websocket data in 30 seconds, checking the connection

After updating to 0.84.5 (now on 0.84.6 still same issue)
I get the below error msg every 30 sec to 1 minute.

Think it have something to to with the Harmony fix but i still get this error after disabling the harmony component. Anyone else with same error?
