nginx: TLS only setup: "Assessment failed: Unable to connect to server"

I was trying to move a server to a TLS-only setup.

 

nginx.conf:

 

[previous]

ssl_protocols TLSv1.2 TLSv1.1 TLSv1 SSLv3;

 

[TLS-only]

ssl_protocols TLSv1 TLSv1.1 TLSv1.2;

 

After the change, I am unable to use the SSL Report tools again:

 

https://www.ssllabs.com/ssltest/analyze.html?d=go.ksz.ch

 

"Assessment failed: Unable to connect to server"

 

openssl s_client -port 443 -debug ... does not show any problems. IE, Firefox, Chrome and Opera are still able to access the site.

 

What am I missing?

 

Best regards,
