This happens:
1.The web inspector does not select the right target automatically,you might do it manually in the Remote panel please
check this video.also if it lose connect,please refresh your page and reload web inspector,this is how weinre works,also see
how to use weinre.
2.The web inspector requires a server which I deployed at Landon,if your location too far to load the request,you can switch the server to your own,
please check the “Switch weinre Server” command in HTTP Server to see how to switch server :)
