let's encrypt error while creating a certificate

[ericosman]

Hey all,

When i want to create an let's encrypt certificate i get this error message:

Error: http://imap.mydomainhere.com/.well-known/acme-challenge/letsencrypt_1587457607 is not reachable. Aborting the script.
dig output for imap.mydomainhere.com:
Please make sure /.well-known alias is setup in WWW server.

A way i found to fix this is creating an A record with the following info (but i don't think this is the right way....):

Type	Name	Value
	A	*	SERVERIPHERE

This is in my Directadmin.conf

letsencrypt=1
letsencrypt_list=www:mail:ftp:pop:smtp:imap:webmail
letsencrypt_list_selected=www:mail:ftp:pop:smtp:imap:webmail

Does anyone have an idea what could be wrong?

For all included in generated cert subdomains must exist correct DNS record, and all them must point to server where You run letsencrypt script.
In Your case - check subdomain IMAP
