GDO BLAQ locks up Liftmaster 8500W with MYQ and Homelink

We have one tesla that uses homelink and one uses MYQ. Every few days after one car opens or closes the door then the other opens or closes the door, the GDOBLAQ locks up, blue light light flashes and the 8500 will not respond except via the wall button and the GDOBLAQ will not respond to the Konnected app (shows the yellow triangle) and of course neither MYq, Homelink , Home Assistant will not connect to the BLAQ. There is a maximum wifi signal as the Meraki access point is 20 ft away. If I reset the BLAQ it seems to wok for a couple of days.
