Hi,
Would you mind contact me directly? I send a pm to you, thanks

Ok, thanks for e1_scheer's help, we finally found the root cause, the reason is an unknown application occupied the port 7001 so Axis Neuron can't stream out the data to MotionLIVE, we changed the port to 7011 then it works.
If anyone has the same issue, you could try to download this tool to find the free port, and set it in MotionLIVE and Axis Neuron, thanks

So this all got fixed this morning with everything up and running
and an excellent way to start the new year !

Thanks again Luke
