Custom domain issue

So I’m fairly new to replit and I’m trying to get my flask site up using my own domain but when i click the ‘open in new tab’ button it cant access the site and it shows ‘ERR_CONNECTION_CLOSED’.

It says my domain is verified and I checked using the site
so id like some help to understand why its not working when it says it should be.

Btw the site shows up in the WebView tab but not in the normal web browser.
