No SNI support on multisite installation

[Saint Michael]

I have an openresty server, latest, compiled with http_ssl. So I have
5 websites on the same IP, each one with a server block, a listen
statement XXXX:443 SSL; and its own server_name but when I test any of
the certificates (example https:// 3y3. us), the online analyzer
https://www.ssllabs.com/ssltest/ says that there is no SNI support,
"This site works only in browsers with SNI support."
" Certificate #2: RSA 2048 bits (SHA256withRSA) No SNI

so how do I avoid this issue? Is there anything missing in my
configuration? I need to use the same IP for every website.
