Preview / Debug page wont load

I get this error when trying to load a preview (on any page), but the live site works fine… not sure what’s wrong?

" This site can’t be reached
demobros.co unexpectedly closed the connection.
Try:

  • Checking the connection
  • Checking the proxy and the firewall
    ERR_CONNECTION_CLOSED

I built an app 4 years ago on a custom domain that i never finished, then just yesterday I wiped all the content and started building essentially a new app but with the same domain as before. I just tried updating to a later version of bubble and that didn’t help. Also tried different browsers.

Looking at the DNS settings in godaddy but not really sure what i’m looking for.

Thanks for any help trying to fix it!

(app link should just be http://demobros.co)

OK nevermind, i had to check the SSL box apparently. Classic that i spent like 2 hrs looking for a solution then found one minutes after posting this. haha
