Failed authorization when renewin cert

Hi everybody,

So this morning when I tried to go on my website, I got a Privacy error, apparently my cert is expired, so I tried to renew it with the commande “./opt/letsencrypt/letsencrypt-auto --expand”, I selected my domain, and i got this error message :

“Failed authorization procedure. (tls-sni-01): urn:acme:error:connection :: The server could not connect to the client to verify the domain :: DNS problem: NXDOMAIN looking up A for”.

Renewing my cert worked in the past, so I don’t know why it won’t work this time.

My domain is:

I ran this command: ./opt/letsencrypt-auto --expand

My operating system is (include version): openSUSE 13.2 (Harlequin) (x86_64) 64-bit

My web server is (include version): Apache 2.4

I can login to a root shell on my machine

It fails for the reason it says - " DNS problem: NXDOMAIN looking up A for".

If I try and go to your domain -

curl -I
curl: (6) Could not resolve host:


Host not found: 3(NXDOMAIN)
