Looking at the error … you tried to get certificates for a couple of domains … the one you left on the screen, and the one you ‘erased’. The one that was ‘erased’ has a problem being reached by LE.
Is that domain hosted on your account ? is it reachable for the general public ?

Alternatively you may want to use a different client ( alternative clients )
