PTP450i Cannot ping remote radio

Hi all,

As per diagram picture, this is weird and 1st time happening to us.
We already look inside the radio setting and can find anything that don’t allowed ping to master/ remote radio.

We can access both gui, but the one that we can’t ping we can access it using the LUID link inside the gui interface.

Usually we find this setting in the radio but we cant find it.

it only show this in the setting

we are using the latest firmware CANOPY 22.1.1 BHUL450
