I do:
openssl s_client -connect website.com:443 -tls1_1
And get:
CONNECTED(00000003)

I also get something like this when testing TLS 1.0.
However, testing TLS 1.2 is successful
The website config (nginx) includes this:
server {
listen 443 ssl;
listen [::]:443 ssl;
server_name website.com www.website.com;

Have no idea what's going on! Any suggestions?
Thanks!
