Certified Installation Error

During the certificate installation I get the following error:


  • The following errors were reported by the server:

    Domain: www.pippo.com
    Type: malformed
    Detail: Failed to connect to XXXXXXX:443 for TLS-SNI-01
    challenge: Server only speaks HTTP, not TLS

    To fix these errors, please make sure that you did not provide any
    invalid information to the client, and try running Certbot again.

I have Ubuntu 15.04 server but I do not think this is the problem because on another server with the same version runs properly.
How can I do?


hi marko

you should review the challenge types and the syntax

if you are using the standalone method then you need to make sure that there are no other webservers running

alternatively you can use the DNS and http challenge.

there are many articles on how to do this in this forum
