PMP 450i AP update 20.3.1

I’m having problems updating PMP 450i AP to firmware 20.3.1. I was able to update the SM’s but the AP is still on I’m using CNUT and haven’t had issues updating in the past. I also tried to update on a separate network and I’m having the same issue.

CNUT from command line or GUI?
From command line IT WAS (dunno now) bugged, and stopped perché asked something… from the gui.

Never mind I had to update to CNUT 5.0 and this resolved the issue
