Sophos XG HA Active-Active mode vMware Primary IP not working



I managed to setup my firewalls in Active-Active mode but the primary ip doesn't respond to either ping or https. I can only connect to the auxiliary FW using the secondary IP but it is on read-only mode.


Environment details.

vMware ESXI 6.7

Cisco L3 router 37xx

Sophos XG 17.5 GA


Thanks in advance.
