EspruinoHub/WebIDE: Command Disallowed (0xc)

G'day everyone,

Just wondering if anyone has come across this error before while trying to connect from the WebIDE?

I can see the PuckJS but am unable to connect. The following is from the Pi status page served from the EspruinoHub.
I have also just updated the EspruinoHub and WebIDE running on the Pi as well as my PuckJS to 1V95.

I'm using an RPi3 with external an bluetooth adaptor and the WebIDE from another linux machine.

Until now I have just been using the EspruinoHub with Node-Red for some control based on clicks but since the WebIDE was added it would be a great way to reprogram them too.

Any help would be great.

Cheers
Ryan
