Please make my domain work

The only reason I can think of which would explain this issue is DNS caching. Which the client area also tells you about: Note that it says “which InfinityFree cannot control”. So no, we cannot make your domain work. Your domain name itself is already working. If you’re not seeing it yet, that’s an issue on your end and only you can solve that. To learn more, go to the client area and click that Learn More button.
