2015	Directive 'ssl_protocols' doesn't work on server blocks	mhernawan		"I have multiple server blocks on nginx configuration.
First, server block default with TLSv1.2. I use this to handle API on my public IP address (https ipaddress).

**Here is the configuration file:**
{{{
server {
        listen 80 default_server;
        listen 443 ssl default_server;
		ssl_protocols TLSv1.2;
        root /var/www/html;
        index index.html;
        server_name _;
        ssl_certificate /etc/ssl/default/full.crt;
        ssl_certificate_key /etc/ssl/default/private.key;
}
}}}


Second server block to handle my domain https://itkoding.com/ and i set it to use TLSv1.3.
**Configuration file:**
{{{
server {
        listen 443 ssl;
        ssl_protocols TLSv1.3;
        root /var/www/itkoding;
        index index.php index.html;
        server_name itkoding.com;
        
		....
		....
		....
}
}}}

**The result:**
https ip address uses the right ssl protocol (tlsv2)
But https my domain uses wrong ssl protocol (tlsv2).
If i change server block default to TLSv1.3 both ip address and domain use tlsv3. So, ssl protocol can be changed only in server block default."	defect	closed	minor		nginx-core	1.8.x	duplicate	ssl, ssl_protocols		Linux myserver 5.4.0-40-generic #44-Ubuntu SMP Tue Jun 23 00:01:04 UTC 2020 x86_64	"nginx version: nginx/1.18.0 (Ubuntu)
