How to Clear Chrome Net Internals DNS Error?

What Is the Chrome Net Internals DNS Error?

The Chrome Net Internals DNS error occurs when Google Chrome encounters issues resolving a website's domain name. This problem can arise due to cached DNS records, outdated settings, or network misconfigurations. The error can lead to websites failing to load properly, displaying messages like "DNS_PROBE_FINISHED_NXDOMAIN" or "This site can't be reached."

Why Does This Error Occur?

Several factors can contribute to the Chrome Net Internals DNS error:

• Corrupt DNS Cache: Chrome stores DNS records to speed up browsing, but old or incorrect records may cause issues.

• ISP or Router Issues: A misconfigured router or ISP-related DNS failures can prevent domain resolution.

• Incorrect Chrome Settings: Some experimental Chrome flags or proxy settings can interfere with DNS lookups.

• Malware or Security Software: Overprotective firewalls or malware infections may block DNS requests.
