openbci-wifi-server problem with /output/json

[testpilot0]

I am trying to GET data from OpenBCI Wifi Server. I run Wifi Shield (connected to OpenBCI) as hotspot and I can issue GET http://192.168.4.1/all from my browser and it return some info (I've pasted it bellow just removing MAC addr)

{"board_connected":true,"heap":19568,"ip":"0.0.0.0","mac":"......","name":"OpenBCI-4CB8","num_channels":0,"version":"v2.0.5","latency":10000}

But it respond with "Route Not Found" if I try to run any of these commands
/command
/output/json
/output/raw

Any way to fix that?
