I've just built up letsencrypt and just have a first step trying to use it,
but got stuck at this problem.
Failed authorization procedure. mydomain (http-01): urn:acme:error:unauthorized :: The client lacks sufficient authorization :: Invalid response from http://mydomain.com/.well-known/acme-challenge/mkRepxXg1tXmZrPoRlCQgMvecVvX4zFTmXE2DB2Z2BQ [220.127.116.11]: 404
Here's the command I used:
./letsencrypt-auto --agree-dev-preview -d mydomain.com --server https://acme-v01.api.letsencrypt.org/directory certonly
do I need to mail to server of my domain to add into whitelist at server ?
And my environment is centOS7 , thanks a lot!
btw , I just realized something and little bit worried with it,
1. do I really need to access into the web server of the domain I used,
or can I use other server to get CA for different domain
2. cuz it needs to log IP as having requested this certificate, but I'm using internal IP, can I use FQDN as a substitution?
