Deployment URL issue

I have deployed a web app with a successful build, using a custom domain.

The home page is visible at the URL expected, as are other pages if I go directly to them - but there are some links which when clicked (despite me now having updated these to the complete URL at the custom domain rather than a relative URL), I get an error such as:

`This site can’t be reached

Check if there is a typo in deployments–


Any ideas?

Can you please link your repl? Also, that url seems wrong, are you sure you got the right url?
