nginx: [warn] conflicting server name

I haven't been able to figure out why I'm getting this error:

nginx: [warn] conflicting server name "stage.mydomain.com" on 0.0.0.0:80, ignored nginx: [warn] conflicting server name "stage.mydomain.com" on 0.0.0.0:443, ignored

My sites-enabled symlink file looks like. I'm not super familiar with this but I'm the only one that has any knowledge on servers. This was copied over from production. I see that port 80 and 443 are duplicated but there are some configuration differences in each block.

server {
  listen        80;
  server_name   stage.mydomain.com;
  return       301 https://stage.mydomain.com$request_uri$is_args;
}

server {
  listen         80;
  server_name    stage.mydomain.com;
  location '/.path/here' {
          default_type "text/plain";
          root /home/username/www/app_name/current/public;
  }
  return         301 https://stage.mydomain.com$request_uri$is_args;
}
