First, welcome to the LE community forum!
I'm sorry to hear that you are having troubles.
But, there really isn't much information to work with.
Looking into the domain, I see that it fails to provide the intermediate cert and causes problems with secure connections.
But that would not stop LE from giving you a cert.
You mention WordPress by Bitnami (not sure if one belongs to the other).
In any case, Bitnami has special instructions for handling cert issuance.
And some WordPress uses have also managed to find/use scripts tailored specifically for their certificate issuances.
Unfortunately, I use neither of them; So I can't speak from first-hand experience.
So...
Did this ever work before, or, is this your first attempt at it?
[on this particular system]
Actually I now see that it has an LE cert issued today.
But it isn't handing out the intermediate cert
