React app on digitalocean droplet axios requests not working on other machines

Hey all I'm having an issue pulling up my website on my desktop. On my laptop where I created the app and did all the code my React app works fine and updates however on other machines only my components/elements load while my axios requests are returning (404 connection refused error). Any tips or fixes? P.S This is my first time trying to deploy an app build to a webserver (digitalocean/NGINX).

NGINX config file

    server {
        listen 80 default_server;
        listen [::]:80 default_server;
        root /var/www/epenn92reactapp.space/html/among-us-reactapp3/client/buil>
        index index.html index.htm index.nginx-debian.html;

  }

        location /v1/api {
                proxy_http_version 1.1;
                proxy_cache_bypass $http_upgrade;

Example axios Route

    const [chars, setChars] = useState([]);
    useEffect(() => {

    const fetchData = async () => {
      try {
        let res = await axios.get('http://localhost:8080/api/v1/character', {
        });
        setChars(res.data)
      }
      catch (err) {
        console.log('error', err)
      }
    };
    fetchData();

  }, [chars.length]);

Server.js file

    const PORT = process.env.PORT || 8080

package.json

    "proxy": "http://localhost:8080/"

I've been reading around for about a day now and I'm just not sure what to do any help would be great thanks!
