Big-IP not recognized by Big-IQ

Dear Techs, I'm in a strange situation where I'm supposed to add both F5 Big-IP with Big-IQ. Both Big-IP and Big-IQ are in same subnet, so firewall isn't a question. The Big-IP are in HA....

One thing more, the big ip we want to add have it's device certificate expire. Is this can be the reason? Also what are the impacts of renewing the device liecense, I believe the HA will break right?

Didn't know but in all cases it's necessary to renew this device certificate to restore iQuery communication and Trusted Device Certificate between the cluster. Maybe it will allow the BIG-IQ to discover it.

why do you want to renew the licence ?

Sorry not license, I meant device certificate. Does renewing device certificate breaks/interrupts HA or production traffic?

I don't think so but I've never tested it, so to be safe, plan the change during maintenance window.
