There's a lot of missing detail here. I can guess a little that it's on Windows but the firewall on the unknown version of Windows can block this. Also, the long discussion at https://wordpress.org/support/topic/the-requested-url-was-not-found-on-this-server-24/ may tell more but as presented, there's nothing to say where the issue is or what you did to get that message.
