How can I allow multiple presto coordinator's urls from NGINX

[nikeshthakre]

I wanna allow two presto urls from nginx. bellow is the configuration of nginx.
presto-1 IP :172.18.0.14
presto-2 IP :172.18.0.12
but only one presto coordinator is running at a time. I wanna allow both presto working.

Below is the content of this file /etc/nginx/conf.d/ssl.conf :

server {
listen 443 ssl;
server_name _;

ssl_certificate             /root/server.crt;
ssl_certificate_key         /root/server.key;
ssl_protocols               TLSv1 TLSv1.1 TLSv1.2;
ssl_ciphers                 HIGH:!aNULL:!MD5;

# Load configuration files for the default server block.
include /etc/nginx/default.d/*.conf;

location /presto-1/{
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";
proxy_pass https://172.18.0.14:8443/;
}
location /presto-2/{
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";
proxy_pass https://172.18.0.12:8443/;
}
location /v1/query/{
proxy_pass https://172.18.0.14:8443/v1/query/;
}
location /v1/cluster/{
proxy_pass https://172.18.0.14:8443/v1/cluster/;
}
location /v1/info/{
proxy_pass http://172.18.0.14:9090/v1/info;
}
}

If I am repeating the location for ip 172.18.0.12 then nginx throwing an error of duplicate location.

location /presto-1/{
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";

}
location /presto-2/{
