Debugging DNS Resolution for rubenflamshepherd.com Domain

269 messages · Page 8 of 14

The trace works perfectly - the issue is **specifically Beanfield's recursive DNS resolver**. The resolution chain is fine: - Root servers ✓ - .com servers ✓ - Porkbun nameservers ✓ - Returns correct IPs ✓ But Beanfield's resolver returns `SERVFAIL` instead of doing this lookup. This could be: 1. **Cached bad response** - Beanfield cached a SERVFAIL from a previous failed lookup (maybe when DNS wasn't fully propagated) and hasn't expired it yet 2. **Resolver bug** - Issue with how Beanfield handles Cloudflare-fronted nameservers (Porkbun uses Cloudflare infrastructure) 3. **Rate limiting** - Unlikely but possible **The fix is simple**: Switch to a public DNS (8.8.8.8 or 1.1.1.1). Beanfield's cache will eventually expire, but you don't need to wait. ```bash networksetup -setdnsservers Wi-Fi 8.8.8.8 8.8.4.4 ``` This isn't a problem with your Porkbun configuration - it's Beanfield's DNS being buggy with your specific domain.

any downside to switching to public dns?

Minimal downsides for most people: **Potential concerns:** - **Privacy** - Google (8.8.8.8) sees your queries and may use for profiling. Cloudflare (1.1.1.1) claims no logging/selling of data - **Latency** - Theoretically ISP DNS is "closer," but in practice Google/Cloudflare have massive CDNs and are often faster - **CDN routing** - Some CDNs use DNS location for routing. Modern public DNS uses EDNS Client Subnet to mitigate this, so rarely an issue **Actually often better:** - More reliable than ISP DNS (as you're experiencing) - Faster cache updates - Less censorship/filtering - Better security (DNSSEC validation) **If privacy matters most:** Use Cloudflare (1.1.1.1) over Google. Or run your own recursive resolver if you're paranoid. For most people, switching to 1.1.1.1 or 8.8.8.8 is a net positive. The Beanfield situation you're hitting is a perfect example of why ISP DNS can be frustrating.

lets switch to cloudflare

Tool: Bash

$ networksetup -listallnetworkservices | grep -v "asterisk"

Tool: Bash

$ networksetup -setdnsservers Wi-Fi 1.1.1.1 1.0.0.1 && echo "DNS set to Cloudflare" && networksetup -getdnsservers Wi-Fi

Done. Let me verify it's working now.

Tool: Bash

$ dig rubenflamshepherd.com +short

DNS is resolving. Let me verify the site loads in the browser.

Tool: Bash

$ cd /Users/ruben.flam-shepherd/.claude/plugins/cache/dev-browser-marketplace/dev-browser/66682fb0513a/skills/dev-browser && npx tsx <<'EOF'
import { connect, waitForPageLoad } from "@/client.js";

const client = await connect();
const page = await client.page("rubenflamshepherd", { viewport: { width: 1920, height: 1080 } });

try {
  await page.goto("https://rubenflamshepherd.com", { timeout: 30000 });
  await waitForPageLoad(page);
  console.log({ title: await page.title(), url: page.url() });
} catch (e) {
  console.log("Error:", e.message);
}

await page.screenshot({ path: "tmp/screenshot.png" });
await client.disconnect();
