I tried to get the certificate with this command /root/certbot-auto --apache
but it failed and this is the error msg
tls-sni-01 challenge for www.projecttoe.com
Waiting for verification…
Cleaning up challenges
Failed authorization procedure. www.projecttoe.com (tls-sni-01): urn:acme:error:connection :: The server could not connect to the client to verify the domain :: Failed to connect to 126.96.36.199:443 for tls-sni-01 challenge
the server is Apache on centos .
I stopped the web server and run certbot in standalone mode , i got the certificate and config vhost to support ssl but when Apache comes up https doesn’t work.
