Nginx subdomain is rerouting to main domain

I have an nginx webserver hosting an old site. This site has been migrated to a new site but I want to keep the old site live on a subdomain, legacy2.example.com. I've gone through and modified the sites-enabled and sites-available config files and linked them, as well as created an A record to legacy2.example.com pointing to this IP, however it is still redirecting to domain.com, not legacy2.example.com. I'm including my config file below. Is there some other config in nginx that could be telling it to redirect?

I've followed along with similar questions and basic guides, but even with changing the server_name field I can't seem to get

    listen     80;
    listen     [::]:80;
    server_name legacy2.example.com wwww.legacy2.example.com;

    }

      return 301 https://$http_host$request_uri;
    }
 }
