DNS_PROBE_FINISHED_NXDOMAIN on Chrome

Chrome keeps its own DNS cache separate from the operating system, so it can show NXDOMAIN after the OS cache has already been cleared.

Why it happens on Chrome

Chrome keeps its own DNS cache separate from the operating system, so it can show NXDOMAIN after the OS cache has already been cleared.

The fix on Chrome

Visit chrome://net-internals/#dns and click Clear host cache, then chrome://net-internals/#sockets and flush socket pools before retrying.

If that didn't fix it

Chrome has its own failure mode, but DNS_PROBE_FINISHED_NXDOMAIN has a wider set of causes. The most common one overall is: The A or CNAME record for the hostname does not exist.

Add the missing record at the DNS provider. Remember that the apex and www are separate records.

Check your own domain

The DNS lookup queries public resolvers directly and shows the A, AAAA, CNAME and NS records that actually exist — which instantly separates 'record missing' from 'my resolver is stale'.
