The DNS_PROBE_STARTED error in Google Chrome appears when the browser begins querying the DNS server for domain name resolution but has not yet received a response. It indicates that the DNS probing process has started but not completed. On the other hand, DNS_PROBE_FINISHED_NXDOMAIN is a Chrome-specific error that occurs when the DNS query fails. It means that the domain name cannot be resolved to an IP address either because the domain does not exist, the DNS server is misconfigured, or there are network-related issues preventing proper resolution.

How to Fix DNS_PROBE_STARTED and DNS_PROBE_FINISHED_NXDOMAIN Errors

Follow these steps to resolve these DNS-related errors in Google Chrome:

1. Flush Chrome’s DNS Cache

Clearing Chrome’s internal DNS cache can fix temporary resolution issues.

1. Open Google Chrome.

2. In the address bar, type chrome://net-internals/#dns and press Enter.

    ipconfig /flushdns
    Windows-Flush-DNS-02

5. Disable VPN, Proxy, or Security Software

If you're using a VPN, proxy, or firewall temporarily disable it and check if the issue is resolved. Some security software blocks DNS queries causing errors like DNS_PROBE_FINISHED_NXDOMAIN.

6. Reset Chrome Flags

If you have modified Chrome’s experimental features, they might interfere with DNS resolution.
