Yeah, it has been an issues since atleast early 2022. I guess none of the site’s admins were paying the reader enough mind to even notice it going out.
If my memory served me right, uboachan’s scanlation group also uploaded their work on mangadex. Maybe you could try to look for YN doujins there?

I think the team's spirits kinda got broken when the popular author of nearly all of the Yume Nikki fanworks we had scanlated requested a takedown. We invested a lot of time and effort (and money) into those and we couldn't understand how it affects the author negatively for us to share scans in another language with people who were never going to see their work otherwise, so it really felt like a slap in the face. Things slowed to a stop in the year or so that followed. Most likely it broke during the server transfer and I missed it. I'll take a look.
