BE88U prevent connection to Multiplicity KVM

[Lilrex]

I am using multiplicity KVM from Stardock software. I tried to replace my Asus AX88U non-pro model router with the Asus BE88U router and the KVM wont connect with the BE88U but will work with the AX88U.

I also checked the firewall on the target machine and the software is in the list, the app is set to secondary, and KVM is not disabled.

Other things I have tried so far:

Factory Resetting the router

Removing the switch and connection both PCs directly to the router

Enabling the DMZ and testing both IP addresses

Port forwaring the Multiplicity documented ports

Double checked all firewall settings in Windows Defender Firewall to make sure no specific settings were enabled for the primary PC to connect

Completely disabling the firewall on the router
