What’s wrong?

I don’t think the installation went well. The website itself isn’t there either. There should at least be a default WP with a “hello world” post.
How did you try to install? Manually or through some automatic process?

No idea how these automatic processes go. Can you try again? Otherwise talk to your host or do a manual install:
