I have no knowledge about Next.js or Vercel whatsoever and I was looking for a discord for help with Vercel, and this popped up. I apologise in advance if this post is irrelevant.

I have a very amateur coding experience and yesterday was the first time I heard about Vercel.

I am not able to get through to a webpage. I am constantly getting a 404 Deployment not found error.

The webpage in question is
www.burgeonbook.org

It used to work, but yesterday I was presented with this error (attached below)

The website is NOT mine and I have not worked on it. Is there anyway I can fix this or work around it, or will it only be resolved when the owner fixes it?
