Read .txt file from my website without enabling JavaScript (C#)

I am trying to read a text file from my website using a WebClient or HttpWebRequest in C#, however they always return that I need to enable JavaScript, when this is just a text file (however, it contains basic HTML)

Is there any way to make my website not need JavaScript for .txt files, or a different method to fix this?

This is what I get (aside from a clunk of html)
This site requires Javascript to work, please enable Javascript in your browser or use a browser with Javascript support

Thank you.

No, you can only host websites on InfinityFree, not API backends. Only clients which support javascript and cookies can access any content hosted on InfinityFree.
