I had exactly the same issue right now on Focal with 20.03.2-0ubuntu0.20.04.1 3 of 6 ovn-controller nodes were reported as "XXX". After restarting all of failing ones, only 2 of 3 reconnected without issues. The last one ovn-controller was still having problems. The only thing which worked was a workaround from #4
