Smartrise help!!!!!! Out of Group

Have a Smartrise group dispatcher intermittently display out of group! And go offline. I downloaded the manuals and can’t find anything about Out of group just Out of service. Is this the same thing, Any suggestion?

The group display is showing one of the elevators as out of group. This means the car is not available to the group. just an indicator not necessarily a fault. Could be a fault, elevator is in a mode not supported by the group such as IND or insp. could be parking, etc. what does elevator control say? check group communication on group control. just like checking floor board communication on car. should be 70% or higher preferable 100%

Update!!!! the Elevator was flickering in and out of group, from normal to OoG, But its fixed now had a communication issue between both cars and Group Board, Elevator has been running for over a years tho..... craziness, Mechanics before have tried everything before they sent a fresh set of eyes, even updating software.....
