Hello,

I am impacted by the security problem of TLS-SNI.

My site runs on Ubuntu apache.

https://www.hightechplace.com/

If I understood correctly on Apache I can not use “–preferred-challenges http”?

./letsencrypt-auto --prefered-challenges http -d hightechplace.com

What is the solution on Apache?

Thanks for your help.

Mathieu

As written in Solution: Client with the currently selected authenticator does not support any combination of challenges that will satisfy the CA , you can use the manual webroot authenticator and use the --installer apache flag.
