Let's say I have the following domains:

example.com in cloudflare

with these subdomains:

test1.example.com
test2.example.com
...
test10.example.com

test1.example.com is accessable with https or http and test2 to test10 are working well with http. I installed letsencrypt wildcard ssl on test1.example.com with this command

sudo certbot --server https://acme-v02.api.letsencrypt.org/directory --manual --preferred-challenges dns  --installer nginx -d nexlabs.better.hr

Here is the issue come. Before I installed letsencrypt, when user go non-existance domains like gggg.example.com and hhhh.example.com, they get served by the standard nginx index.html. After I installed letsencrypt when someone enter domain like gggg.example.com , it automatically redirect to test1.example.com. I don't want to happen like this .
and here is my nginx conf file for this

upstream test1_api {

    server < some_ip >:8523;

}

upstream test1_dashboard {

 server < some_ip >:3523;

}

server {

    listen       443 ssl;

    server_name  test1.example.com;

    access_log  /var/log/nginx/log/test1/access.log;

    error_log  /var/log/nginx/log/test1/error.log;

    index  index.html index.htm;
