Bindings - hostname and SNI required

Server
1

Hi Y’All

I have 40 odd sites running under IIS 10. Recent convert to LetsEncrypt

I need advice on how I should config IIS to use newly generated certs.
Should I set hostname field?
Should I tick Require Server Name Indication
How should bindings on default website be config’d

Your help gratefully received!

You need both.

hostname example.com + SNI
hostname www.example.com + SNI

A certificate with example.com and www.example.com, use this with these two bindings.

But normally the tool you use should do that.
