LuCI inaccessible after setting up a Cudy WR 3000 as a VLAN Access Point

Hi all,

When setting up a Cudy WR 3000 as a VLAN access point, i manage to get everything working, but i cannot access the luci interface or ssh into it once it is set up.

I have another access point that i have set up using exactly the same steps and i can login into it normally.

I am providing the /etc/config/network files on the main router and the first AP that works so you can get an idea of what is going on

The firewall is disabled on both Access points, and i am using a different ip in the second AP (192.168.99.11)

All devices are running OpenWrt 25.12.4

I am stuck, Has this happened to anyone else?
