Renew certificate with expanding domains

[serverco]

@midihipi

Doesn't that mess with letsencrpt auth check when it goes out and looks for a site at that location and finds nothing?

I don't understand what you mean here.

@midihipi

is there a way to check if it contains all?

try the command (where domain.crt is the certificate you want to check )

openssl x509 -in domain.crt -noout -text

or

openssl x509 -in domain.crt -noout -text | grep DNS

if you just want the SANS names.
