MT300AX Gli Gui gone after changing LAN address

Hi,
I try to set up my new Beryl Ax and having a strange issue. I am on latest Gli fw (4.2.2) an when I change the default LAN address of the router I am loosing access to the Gli gui. After applying the changes in the network setting (192.168.179.1), on refreshing the page I do habe the standard OpenWRT gui, but no Gli gui. Reverting back to default (192.168.8.1) the Gli gui is back again?!

What am I doing wrong?

I think if you make the changes in the GLi GUI everything should work. There are some incompatible issue between LuCi and GLi GUI

Unfortunately it‘s not. I did perform the changes within the GLi gui. After applying the IP, the gui changes to OpenWRT gui.
