[CA11] eS78 Network connectivity

Just trying to get my eS 78 set up. using the Wifi Settings i can connecto to my Mobile Hotspot via samsung S9 but it keeps saying connected but no internet access.

I have tested with all my other computers and devices and they all can see the internet through the hotspot. Is there anything I am missing on the config of the MFD?

Any tips would be most appreciated.
Thanks
