Limits retries for upstream servers (proxy, memcached, fastcgi, scgi, uwsgi). Using one of the directives below will enable this feature.

Example

http {
    upstream test {
        server 127.0.0.1:8081;
        server 127.0.0.2:8081;
        server 127.0.0.3:8081;
        server 127.0.0.4:8081;
    }
    server {
        proxy_upstream_tries 2;
        proxy_set_header Host $host;
        
        location / {
            proxy_pass test;
        }
    }
}
