I previously had a pair of custom domains that were validated and set up properly via LetsEncrypt and working. However, I had to destroy & rebuild my stack to get everything into a single repository so I could use preview environments.
I’ve set up my domains now, they are validated, and LetsEncrypt has been pending for 2 hours now. It perhaps has something to do with changing them so soon after establishing them, but I’m not sure what I can do about it.
