Problem with installing LetsEncrypt on Nginx Centos 7 after installing iRedMail

So I installed iRedMail for my mail server, after that I wanted to install LetsEncrypt but it gives me errors.

IMPORTANT NOTES:
 - The following errors were reported by the server:

   Domain: mail.placetoknow.com
   Type:   unauthorized
   Detail: Invalid response from

   To fix these errors, please make sure that your domain name was
   entered correctly and the DNS A record(s) for that domain
   contain(s) the right IP address.

I really don’t know how to solve this problems. Thank you in advance

@Chempo Okay, something is wrong, since the server-block you posted is for your root domain, but the errors in the first post lists 3 subdomains www mail app.

So somewhere there must be more Nginx configuration - if not, then you need to create the server-blocks for the other subdomains: https://www.digitalocean.com/community/tutorials/how-to-set-up-nginx-virtual-hosts-server-blocks-on-centos-6 Skip step 6 about creating a local hosts file.

Hi @Chempo

Can you post your Nginx server block? It’s located in /etc/nginx/sites-enabled/[the name of your configuration].conf
