Linking a composer page

[20fingerspiano]

I am uploading my piano 4 hands transcription on imslp.org.

The overview of what I have uploaded so far appears regularly at my composer page: https://imslp.org/wiki/Category:Castronovo,_Giulio

But when I copy this link in a text, the hyperlink works but redirects the user to a sort of "non existent" page:
https://imslp.org/wiki/Category:Castron ... Sy-oYX_LUM

This happens just opening the link from a computer browser, while from a mobile browser it works fine.

Why?
