Website is hosted, I can access it, but my friend cannot reach it?

I can visit my website run on node.js with my custom domain. However, when my friend tried to do so, he was meet with a "website coming soon" page. The website loads on my laptop, but not his?

I've tried checking if I'm supposed to publish the website or something, but can't find anything. Tried to search for similar problems others had but can't find any of those either.

The website should load for my friend as it did with me.
