I get the following error in console when trying to run the loopback example:

Rebooting...

What does the backtrace say. You have clearly modified the code, so I can't guess at the problem.

No, I didn’t modify the example code.

You have to decode the backtrace if you want assistance. I cannot guess at what the error is.
