for some time letsencrypt always wants to create certificates for subdomains, pop, smtp and mail
I give in the form to which only
www.domain.de and domain.de are created, but letsencrypt always wants to create the subdomains, but these do not exist.
the problem is present at all isp installations at once, because this the creation failed:
***
Failed to verify the domain
return code:400
Details
NS problem: NXDOMAIN looking up A for pop.domain.de
***....
how can i remove this new problems?
