Hi again @clayrabbit,
I can confirm this is a bug on our side. In a nutshell one of your ACME account's authorizations managed to get into a stuck state. We're going to look at addressing the bug that caused this so it won't happen again but in the meantime I have some advice to get you "unstuck".
Do you know if its possible to create a new ACME account using DirectAdmin? If you can reset your Let's Encrypt state, create a new ACME account, and reissue your certificates with that account you should be able to continue without error.
You will also become automatically "unstuck" 2018-07-12 at 21:43:19 UTC but I think we can find a solution for you before then.
Again, apologies for the inconvenience!
