Domain gives 404, cPanel gives error #3998

I recently created two accounts here (btw, why didn’t I hear about this website before? It’s so much better than all the other free hosts), but the first one isn’t working properly.
The second one works perfectly.
When I try to go on the domain name (zdimension.rf.gd) I’m redirected to https://infinityfree.net/errors/404.
And if I try to log into cPanel, I get “error #3998, Please restarting your browser, if this continues contact support 2”. I encountered this problem right after account creation, meaning I didn’t change any setting, etc.
How can I fix this problem?

UPDATE: Ten hours later, it works. I don’t know what was the problem.

Caching issues, most likely. The control panel login issues is likely to have been caused by having multiple control panel sessions open at the time. Try logging out and then logging in to a single account again.

Thanks, everything works fine now.
Btw, thanks for creating this awesome hosting service. Will definitely recommend it to friends.
