DNS_PROBE_FINISHED_NXDOMAIN — What It Means & How to Fix It

✅ Quick Answer (Featured Snippet Style)

DNS_PROBE_FINISHED_NXDOMAIN means the domain name doesn’t exist in DNS (NXDOMAIN = “Non-Existent Domain”).
Fix it by checking nameservers, adding the correct A/AAAA/CNAME records, and waiting for DNS propagation.

What causes NXDOMAIN (most common)

Wrong nameservers at the registrar
Missing A record for @ (root domain)
Missing/incorrect www record (CNAME or A)
Typo in the domain name
Domain expired / not registered
DNS managed in the wrong place (Cloudflare + hosting DNS mixed)

—

Step-by-step fix (do in order)

Step 1 — Confirm the domain is active

Make sure the domain is registered and not expired.
If it expired, renew it first (NXDOMAIN is normal for expired domains).

Step 2 — Confirm you’re using ONE DNS provider

Pick one:

Cloudflare DNS (nameservers point to Cloudflare)
Your host DNS (nameservers point to host)

⚠️ If nameservers point to Cloudflare, you must manage DNS only in Cloudflare.

—

Step 3 — Check nameservers at your registrar (critical)

At your registrar, confirm nameservers are exactly what your DNS provider gave you.

Example (Cloudflare):

xxx.ns.cloudflare.com
yyy.ns.cloudflare.com

If these are wrong → NXDOMAIN stays.

—

Step 4 — Add the right DNS records

In your DNS provider, add:

Root domain

Type: A
Name: @
Value: YOUR_SERVER_IP
TTL: Auto / 300

WWW
Pick ONE:

Type: CNAME
Name: www
Value: @
or
Type: A
Name: www
Value: YOUR_SERVER_IP

—

Step 5 — Wait for propagation

DNS can take:

5–30 minutes (often)
up to 24–48 hours (sometimes)

Test using:

Incognito browser
Mobile data (not Wi-Fi)
Another device

—

Step 6 — Flush local DNS cache (if it’s fixed but you still see it)

Windows

$$
ipconfig /flushdns
$$

macOS

$$
sudo dscacheutil -flushcache; sudo killall -HUP mDNSResponder
$$

Linux

$$
sudo systemd-resolve –flush-caches
$$

2) DNS Beginner’s Guide (Simple, Clear, Practical)

DNS in one sentence

DNS is the internet’s phonebook — it turns a domain name into an IP address.

—

The 7 DNS records you must understand

1) A Record

Points a name to an IPv4 address.

@ → 37.59.215.253

2) AAAA Record

Points to an IPv6 address (optional if you don’t use IPv6).

3) CNAME Record

Aliases one name to another name.

www → @
blog → yoursite.com

4) MX Record

Controls email routing (mail servers).

5) TXT Record

Used for verification and security (SPF/DKIM/DMARC, Google verification, etc.).

6) NS Record

Nameservers — tells the world where your DNS is managed (Cloudflare, your host, etc.).

7) SRV Record

Special services (rare for basic websites).

—

The #1 DNS rule people break

✅ Only one nameserver provider at a time.
If nameservers point to Cloudflare, don’t also edit DNS in the host panel expecting it to work.

—

Recommended “basic website” DNS setup

A @ → your server IP
CNAME www → @ (or A record)
Optional: AAAA (only if using IPv6)

—

Propagation (why “it works for me” happens)

DNS changes spread across the internet over time. Some locations update fast, others slow.

—

DNS troubleshooting checklist

Nameservers correct?
A record exists for @?
www record correct?
Domain active (not expired)?
Using Cloudflare proxy or DNS-only correctly?
Cleared local cache?
