Page links to web host

I recently created a page within my blog.
https://myblog.com/contact
However, when you click on it it links back to my web host (bluehost) Which has a page showing that the page is under construction.

I have an “about” page that is set up the exact same way:
https://myblog/about
It works just fine…

Is there something I am doing wrong or do I need to contact Bluehost?

Thank you
