BT Home Hub Localhost access not working

[Erm yeah that’s hard to pick one]

Got a BT Home Hub on FTTP 1Gb service. Have a small Trigkey G4 N100 PC running Linux. On the machine it’s self I can access localhost:8888/map.html no problem. On my
Phone or laptop over WiFi (local network) I can’t. Even if I try the IP of the device 192.168.1.223:8888/map.html still not able too. I’ve rebooted the hub incase was some strange CACHE issue but no joys. Any idea.

Cheers

Does it have a WLAN Management/Access setting? Sure I've had routers in the past with this option.

It’s pretty basic and normally stuff just works.
