I'm not sure what is your point here? nginx have built SNI a decade ago even CentOS have nginx updated version.

If my nginx not have enabled or not SNI support then why works with www?

Can you enlighten me what i do wrong or what is the "special" configuration to use SNI with shared IPv4 address.
