Whenever I put an internet archive download link into jdownloader, it says it's offline and not available, but it works for me when I click on it in a browser. How do I make jdownloader recognize it as "online files"

Ive been sreaching continuously for more than 3 hours rn trying to download this book called (Ready to print: Handbook for Media Designers)

I have it borrowed for 16 days and it showed and option to download as an LCP PDF which is the first time i've come across sth like that. Downloading the file results in a .Icpl file. I tried searching for ways to convert that file but all my metiods failed.

At the end i came across JDownloader 2 and i had hope but was soon crushed to find only 11/286 jpegs actually downloaded with the others showing an error of "Offline Files".

I tried to search for ways to override that but cant seem to understand how. I also found people saying sth along the lines of copying the .php file from Network in Inpector on the website then pasting it to terminal and adding an O at the end and it should download but doing that resulted in nothing on my end so idk if i'm doing sth wrong.

It's 5 am atp and i'm both tired and desperate, any help would legit be appreciated. Thank you all lovely people in advance < 3
