I am newbie with visual studio code and meet this problem. I code a very simple program and trying to open it by live server and tried to check it by ipad, iphone or some mobile.

But, my problem is, when I changed my code, each time I changed it, and opened my code, it said to me that I had this problem : ERR_INTERNET_DISCONNECTED and when I open it by dimensions (ipad or iphone), it seems very different as the design.

I tried some videos but none of them seems to work
