Beep boop, I’m a bot! I dug through the forum to get you started. I sometimes get things wrong though, so do with this what you will until a human has a look.
The domain on your hosting account (the one with website IP 185.27.134.101) is spelled slightly differently from the one in your post. One letter in the word “library” is different. Can you open the account in the members area and check exactly how the subdomain is spelled there? If it isn’t the same as the address you’re visiting, that would explain why the “domain isn’t connected to an active hosting account” page shows up.
I also can’t tell from the topic where the homepage appears when it does load. Which exact address is it on, and does it work on another network or in a private window?
Your account is only a day old, so it’s also worth reading this article on new domains and DNS answers that get remembered for a while. It says that can take up to 72 hours to settle, and it covers how to flush your DNS cache:
I haven’t found anything that explains the 185.27.134.24 address you got from Google DNS. Once you’ve checked the spelling, post what the members area shows, and a person can look at it if it still doesn’t add up.
