How to enable back TLSv1 and TLSv1.1 on nginx?

My nginx confid files looks like:

 server {
   listen          80;
   listen [::]:80;

   server_name hostserver.ru www.hostserver.ru;
   return 301 https://hostserver.ru$request_uri;

   server_tokens off;
  }

 server {
   listen 443 ssl http2;
   listen [::]:443 ssl http2;
   server_name     hostserver.ru www.hostserver.ru;

   ssl_certificate /etc/letsencrypt/live/hostserver.ru/fullchain.pem;
   ssl_certificate_key /etc/letsencrypt/live/hostserver.ru/privkey.pem;
   ssl_dhparam /etc/ssl/certs/dhparam.pem;
   ssl_session_timeout 1d;
   ssl_session_cache shared:SSL:50m;
   ssl_session_tickets off;
   ssl_protocols TLSv1.2;
   ssl_ciphers 'ECDHE-ECDSA-AES256-GCM-SHA384:ECDHE-RSA-AES256-GCM-SHA384:ECDHE-ECDSA-CHACHA20-POLY1305:ECDHE-RSA-CHACHA20-POLY1305:ECDHE-ECDSA-AES128-GCM-SHA256:ECDHE-R$
   ssl_prefer_server_ciphers on;
   add_header Strict-Transport-Security "max-age=31536000" always;
   ssl_stapling on;
   ssl_stapling_verify on;

   root /var/www/html;
   index index.html index.htm;
   server_tokens off;

   ... some location stuff...
}

Ufortunatelly, TLS1.2 not supported by Android 4.0-4.3 and I've chanched config:

   ssl_protocols TLSv1 TLSv1.1 TLSv1.2;

But after using SSLTest it shows me report that TLS1 and TLS1.1 are not supported.

Did I missed smth to change in config files? Thanks in advance.

UPDATE: I've checked certificates by command:

openssl s_client -tls1 (and so on) -connect example.org:443 < /dev/null

and certificate enabled for each protocol.

I don't know which ciphers work with TLSv1 and TLSv1.1. But I notice from testing sites with SSLTest, that the GCM ciphers are listed against TLSv1.2 only.

You may need to use a more inclusive list of ciphers.

For example:

ssl_ciphers "EECDH+AESGCM:EDH+AESGCM:AES256+EECDH:AES256+EDH";
