LE Cert expiry warng message - Has something changed?

SYSTEM INFORMATION

this warning just popped up

it came as a surprise as this VS has gone through years of renewals without a problem.

On investigation I came across the changes to the certificate request page - nice touch BTW - now displaying the error message on refusal.

this cert has some 31 sub servers listed and the failure was pointing to one sub server xxxxxx.xyz which ha been deleted a while back.

I thought that deletion should remove all references?

Now that new option “Skip unverifiable hostnames” solved the problem

would this be better defaulting to ‘yes’?
