I've bought my deco M4 a month ago and it has been connecting smoothly

Until recently my deco is in red signal and there are no internet connection at all despite I reset and reboot it many times.

I'm using Unifi and it is connecting smoothly, just that my Deco doesnt have any internet.

my deco is connected to Unifi modem and here are my Deco settings:

IPV4: Dynamic IP

ipV6: Disabled

IPTV/VLAN: Enbled- ISP profile: Malaysia-TM Unifi (Doesnt make a difference even if I set up by disabling this option)

Mac Clone: Disabled

TP-Link DDNS: Disabled

SIP ALG: Enabled

UPNP: Enabled

Fast Roaming: Enabled

Beamforming: Enabled

Operation mode: Wireless router

Kindly help me, I've been trying to configure it for a few days and TPlink hotline is not picking up my call
