I thought a 404 was just a missing page, not a project issue?

A) The log project (Project) does not exist is a common reason for a 404.

Wait, could it really be C? I thought 404 was just a missing resource.

I’m not so sure about B, could be a stretch for a 404.

Could it be D? I mean, a busy server might return a 404 if it can't process the request, right? But I'm not confident about that.

I feel like I've seen a similar question before, and it was about server errors. But 404 seems more about missing resources, so I lean towards A.

I'm not entirely sure, but I think B could also be a possibility if the signature is wrong.

I remember studying error codes, and a 404 usually means "not found," so it might be A, the log project doesn't exist.
