Domain transfer from Hostinger to Square and now my page can't connect

[DartPS]

Built a website and domain on hostinger and since we do all POS and inventory on square, I thought it would be a good idea to have everything all together. I transferred the Domain to square, it said successful and connected, yet my webpage is still down and when I try to connect to the domain in settings it lets me select my company but then never actually connects to it and my page remains down. Spoke to Hostinger and my domain has already propagated. Any ideas about next steps?
