Fail to get certificate

Dear all,
I am writing to you because I need your help on getting a certificate.
I am receiving the following error …

c:\caddy>caddy.exe -host example.org
Activating privacy features…2017/05/17 17:41:51 [example.org] fai
led to get certificate: acme: Error 403 - urn:acme:error:unauthorized - Invalid
response from http://example.org/.well-known/acme-challenge/jOwqye1
yXzv1-tQBS1fgi0[example.org]: 404

Best,
George

Hi George,

LetsEncrypt is telling you that it tried to connect to example.org and requested .well-known/acme-challenge/jOwqye1yXzv1-tQBS1fgi0 but was given a 404 error in response.

Since Caddy handles the ACME challenge-response automatically, and a 404 error indicates that some web server did indeed respond (albeit with an error), the most likely problem is that the DNS A record for example.org points to a different server than the one you are running Caddy on.

Hello,
Thank you very much for your reply and your help!
The problem was the skype which was using the ports 80 and 443.
Best,
George
