5. Fix DNS_PROBE_FINISHED_BAD_CONFIG error via VPN
Before you decide to reinstall your operating system, we have a final suggestion. Why not hide your identity and location as a solution to the DNS_PROBE_FINISHED_BAD_CONFIG error? In other words, get access to a VPN (Virtual Private Network) or create your own. If it works, you can run a VPN continuously and use split tunneling to check when to disable it.
Alternatively, exchange your default Internet browser for other browsers with a VPN. On the other hand, if you’re already using a VPN, disable it shortly or change your VPN service provider.
6. Clear your browser cache
The browser cache exists to record data that can aid users the next time they visit the website, so that the browser can remember them and use the saved data to load websites much faster. But caches accumulate over time, and the more websites you visit, the higher the chance of data corruption.
So, when the browser uses this corrupted cache to load data, it can cause an issue with the DNS. Thus, in theory, clearing out your browser cache will help fix the problem and even prevent it from happening in the future.
7. Flush DNS cache
There is also a DNS cache, whose primary task is to record the IP addresses of websites when you visit them. Even when you change the DNS server, the data is updated automatically, thus allowing you to reach the correct address.
But, if your system is configured to store the cache locally and relies on it to establish a connection, chances are the cache will become outdated over time. Thus, flushing a DNS cache is actually resetting this local cache, which can solve your DNS_PROBE error. You may also try changing your DNS to one of the best DNS servers available.
8. Request a new IP address
There’s actually another simpler way to solve this issue, and that is by just renewing your IP address. If you request a new IP address for your system, it will reset everything, and thus, you can use the internet as you normally would. All you have to do is
- Go to the Start menu and launch Command Prompt as an administrator.
- Enter the following command: ipconfig/release.
- Then, request a new IP address using the command: ipconfig/renew. And you are done.
Different types of DNS_PROBE Errors one should be aware of:
Here, we have listed a few different types of DNS_PROBE errors and their causes:
|An error where the DNS server is not responding correctly
|Network issues, Browser cache problems, or router settings interference
|An error associated with Domain names, when DNS can’t resolve the query
|Incorrect URL address, DNS server issues,
|It shows you’re not connected to the internet, even when you are
|Network issues, DNS server settings
|When the website you are trying to connect does not have the same DNS records as what you do, or its domain name has already expired, it will return an error
|Website configuration issues, or an expired domain name
|Basically, it shows that a domain doesn’t exist
|DNS server issues
|When it acknowledges that a connection is established but with limited scope, such as a network connected without Internet access.
