Never heard of the site, so I clicked on the link to see, and got a login page.
Looking at your link
https://www.royalroad.com/fiction/submission/edit?id=29441
Looks like that's a link for you to edit your story (see this path: fiction/submission/edit), and not a link for reading it

Here's two reader links:
This one takes you too the title page;
The Sacrificial Boy by Elizabeth Leigh(AKA Elsbeth on BigCloset TopShelf AKA Branchwraith on Royal Road)

This one is the Start Reading link, and takes you to Chapter 1
Start Reading: The Sacrificial Boy by Elizabeth Leigh(AKA Elsbeth on BigCloset TopShelf AKA Branchwraith on Royal Road)

Apart from the chapters receiving titles, the story appears unchanged, except it abruptly stops after 5 chapters.

Chapter 1: The Black Monolith
Chapter 2: An Unwanted Invitation
Chapter 3: A Knight of Misunderstandings
Chapter 4: A Secret Revealed
Chapter 5: Lies and Secrets

I'm slightly confused by the tags HIATUS, which implies the stories on hold, but is that after five chapters on Royal Road's last post of 11/11/2019, or the 20 Chapters on BCTS last one being posted 13/10/2013?

I haven't read the story yet, but will if it's finished.
I don't want to start reading it, if the BCTS version is also on Hiatus, and incomplete.
