"Error getting validation data"

Help

My domain is: racknet.noip.me

I ran this command: sudo certbot --apache

It produced this output:

rackover@rackover-CHADNET:~/APACHE2/gameservices⟫ sudo certbot --apache

IMPORTANT NOTES:

  • The following errors were reported by the server:

    To fix these errors, please make sure that your domain name was
    entered correctly and the DNS A/AAAA record(s) for that domain
    contain(s) the right IP address. Additionally, please check that
    your computer has a publicly routable IP address and that no
    firewalls are preventing the server from communicating with the
    client. If you're using the webroot plugin, you should also verify
    that you are serving files from the webroot path you provided.

The operating system my web server runs on is (include version):

Distributor ID: Ubuntu

I can login to a root shell on my machine (yes or no, or I don't know): Yes

Hi @Rackover

the tls-sni-01 - validation is deprecated, support ends 2019-02-13.

So you should change your validation method.

Try

sudo certbot --apache --preferred-challenges http

Hi, thanks for your reply.
It does not work neither, but at least the error is different.

Your main configuration

looks ok. So you have redirects.

Check your apache config to find your webroot / DocumentRoot.

Then create a file (file name 1234) in /yourwebroot/.well-known/acme-challenge and try to load this file via

http://racknet.noip.me/.well-known/acme-challenge/1234

If this works, you have your correct webroot. So use

certbot run -a webroot -i apache -w yourWebRoot -d yourdomain.com
