All APs offline after updating

APs were on 2.2e, and attempted to update them. They are on 2.2d now, but all show offline. I’ve tried restarting them via cycling POE power.

I don’t want to really reset them as they are in high to reach/obscure places.

Any help would be appreciated

Hi @Oceges ,

I just replied to your support ticket on the same situation. Would you prefer to continue here or on the support ticket?

For the sake of updating the community, we resolved this via the support ticket.

The DNS servers that the APs were using had gone down at some point. Upon realizing this and restarting the services, the APs are communicating again. It would seem as though the firmware upgrade itself was a red herring.
