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

Question

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";
