Palo Alto 2020 not passing traffic through to servers 2nd IP address

Hi there,

Got a problem whereby one of my servers has a second IP address assigned to it for High Availability and for autodiscovery. However, from time to time the Palo Alto just stops connections passing though to it, so we cannot ping that second address and we lose connection to anything trying to find it. But it can still ping and get to the primary IP address.

And this is for all networks/security zones except those that are in the same server zone and plugged into the same switch as the server in question (before it then connects to the Palo Alto obviously)

Anyone else come across this or able to point me in the right direction?
