ZenWifi XT8 - Cannot connect remotely

[Mantorok]

Battery or AC: AC
Model: ASUS ZenWiFi AX (XT8)
Frequency of occurrence: Always
Reset OS:

Firmware: 3.0.0.4.386_46061
========================
Detailed description：
I'm not able to remotely connect to the router. This includes using the "ASUS Router" app on my iPhone and using the remote access url in the "Administration > System" tab (under the Remote Access Config section). It works fine when I'm connected to the LAN.
The "Enable Web Access from WAN" option is set to "Yes"
Also, port forwarding is not working either.
I've tried running a traceroute and after a few hops I just get the 3 stars (* * *) continuously.
I thought it may be a firewall issue but disabling it makes no difference.
Any help would be appreciated.
