The issue seems to be with your web server serving the page if you look at your message it says the content-length is 162

That should be the length of the file, which is a lot more than that, so I don’t think your web server is returning the correct stream for the URL.
Rather than trying to serve the file from your own web server why don’t you just try typing;
installnxpanel
That will download it from mine, which I know works.
Short of that, you’ll need to adress why your webserver in not returning the right thing.
you could uncomment this line in the berry file;
Which would show you what your headers are, might give you a clue.
