Centos 6 Multiserver setup. lets encrypt is working for many years, Also today it created 4 new certificates for 4 new sites withoud any problems. But: I have one domain that stopt working. The 443 section is gone in the config. When checking letsencrypt it is not creating the 443 section. When only checking SSL, create a self sign certificate it is working. Treid to remove the letsencrypt files for this domain. Then a new certificate is created. The symlinks in /domein/ssl is created. But not the 443 section :-( any idees?
