Unable to link Mit 2 Companion App

I had been trying to make an app that to show a lot info between pages. I code my apps into html method so it can navigate between pages using WebView components. Now I have a lot html file and image, and I made them into folder type and uploaded to http://code.appinventor.mit.edu/ server. Total aia file size is 36mb and made up of 736files. However, when I am trying to link to my companion, my phone always shows unable to load one of the file from the assets. Is there anyway I can solve this issue ?
I am using Ethernet connection in my PC
My phone connecting wifi
Internet speed 100mbps
