Let's Encrypt certificates not generated

Two days ago I moved three of my static sites from GitHub, they each have a custom domain and use the plain HTML CI template. Of the three only one has had its SSL certificate generated, the other two are stuck.

There doesn’t seem to be a way to fix this myself, how can I get my sites working again?

Edit: honestly not sure if this is the correct place to bring this up, instructions for contacting support of any kind are piss poor.

Edit 2: Ah ok. It is possible to open a support ticket without paying for technical support, it’s just explained in such a way that it reads like you need to pay.
