"TypeError: NetworkError when attempting to fetch resource." when using web interface.

[ThisIsNetsu]

First of all, this thing is amazing. But for me it only works when I run the start.bat.
When I try the web interface I get

"TypeError: NetworkError when attempting to fetch resource."

and then the terminal window:

After that it keeps repeating

over and over.

At first I thought I had installed something wrong, but the non web interface version seems to work just fine.

Any idea what this could be?

I also have the same issue when running the "StartWeb" script.
