🗣 Wd提问: dns_PROBE_FINISHED_NXDOMAIN

🤖 Ai回答:
The error dns_PROBE_FINISHED_NXDOMAIN is a DNS (Domain Name System) error that typically appears when a web browser is unable to resolve a domain name to an IP address、Here's a breakdown of what this error means and some potential solutions:

What does dns_PROBE_FINISHED_NXDOMAIN mean?

DNS: The Domain Name System is like a phonebook for the internet、It translates human-readable domain names (like www.65.hk) into IP addresses (like 192.0.2.1) that computers use to identify each other on the network.
PROBE_FINISHED: This indicates that the browser has completed its attempt to resolve the domain name.
NXDOMAIN: This is a DNS status code that means Non-Existent Domain、It indicates that the domain name you're trying to reach does not exist in the DNS system.

Common Causes

1、Incorrect Domain Name: You might have mistyped the domain name or entered a domain that doesn't exist.
2、DNS Server Issues: The DNS server your computer is using might be down, misconfigured, or unable to resolve the domain name.
3、Network Issues: There could be problems with your network connection, such as a firewall blocking DNS requests or a router issue.
4、Hosts File: Sometimes, the hosts file on your computer can be misconfigured, leading to DNS resolution issues.
5、Browser Cache: Your browser might be using a cached DNS entry that is no longer valid.

Solutions

1、Check the Domain Name: Double-check the domain name you're trying to access、Make sure there are no typos.
2、Clear DNS Cache: Clearing your computer's DNS cache can help resolve the issue、Here's how to do it on different operating systems:
Windows: Open Command Prompt and type `ipconfig /flushdns`.
macOS: Open Terminal and type `sudo killall -HUP mDNSResponder`.
Linux: The command can vary depending on the distribution、For example, on Ubuntu, you can use `sudo systemd-resolve flush-caches`.
3、Change DNS Server: Try using a different DNS server, such as Google's public DNS (8.8.8.8 and 8.8.4.4) or Cloudflare's DNS (1.1.1.1)、You can change your DNS settings in your network adapter settings.
4、Check Network Connection: Ensure that your network connection is stable and that there are no firewall or router issues blocking DNS requests.
5、Check Hosts File: If you have modified the hosts file on your computer, check it for any incorrect entries related to the domain you're trying to access.
6、Restart Your Browser and Computer: Sometimes, simply restarting your browser or computer can resolve the issue.

If the problem persists after trying these solutions, it might be a problem with the domain itself, and you should contact the domain owner or hosting provider for further assistance.
