Page not rendering despite providing token

[daniel-althoff]

Hi,

I am trying to preview an HTML from a private page.
The link is the following:
https://raw.githubusercontent.com/daniel-althoff/....file.html?token=....

So I tried:
https://htmlpreview.github.io/?https://raw.githubusercontent.com/daniel-althoff/....file.html?token=....

The page does not render... it just turns blank.
However, when I copy the code from the raw HTML file to jsbin.com, the page renders.
If I put the HTML file in my github.daniel-althoff.io folders, it also renders.

If you need the right path and token to test, let me know.

Help please :)
