3000L gone deaf?

Had a 3000L operating no problems until today when abruptly all the subs dropped and didn’t come back. Not much telling in the logs (aside from subs disconnecting), the neighbouring radio on the same tower can still hear the noise from this one but what does seem telling is the spectrum analyser doesn’t seem to be showing much of anything, in what is a very busy area RF wise.

This happened to anyone else?

Nobody else reported so far either in community nor through Tech Support Tickets.
Has the reboot solved the issue?

Thank you.

Not likely deaf, but very likely its in hold off mode. Our e3k-L APs do this when in hold off mode.
Also check that you are using detailed spectrum scan or it can sometimes take a very long time to populate the background noise as it is below the -90 threshold.
