Why is my app not resolving .gov domains?

App Platform apps may be slow or unable to resolve .gov domains because the domain administrators have blocked DigitalOcean’s IP addresses. To fix this, you can contact the domain administrator or use a custom DNS resolver.

For example, if you are using the example.gov domain, you can use the following code to set Cloudflare’s DNS server as the resolver in your Node.js application:

const dns = require('dns');

// Set Cloudflare's DNS server
dns.setServers(['1.1.1.1']);

const agent = new https.Agent({
  lookup: (hostname, options, callback) => {
    dns.lookup(hostname, options, callback);
  }
});

// Example usage with axios
axios.get('https://example.com', { httpsAgent: agent })
  .then(response => {})
  .catch(error => {})

We recommend using a custom DNS resolver only to query the .gov sites that have resolution issues. Setting the custom resolver as the default resolver for your app can cause connection issues to DigitalOcean Managed Databases connected to the app.
