Hello.
Sorry, I am really very weak in this field...
My Let'sEncrypt certificate is going to expire. As recommended, I run "dehydrated -c". But it tried to authorize all my mail addresses and all internal computer names ever seen on internal network. Obviously this failed.
I found that file domains.txt in the /etc/dehydrated/ directory contains about 40 names instead of 1 as per my understanding.
I deleted all unnecessary names leaving only my domain name and now dehydrated passed successfully and updated my certificates.
Although it is not a problem for me once in 3 months to restore the domains.txt content, I am curious what is incorrect? Why someone fills this domain.txt with all existing and once-existed names?
Thanks for the help.
P.S. The very similar (if not identical) list of names I found in the file /etc/openssl.conf. which says in capital letters "Don't modify this file"...
