[errno -2] Name or Service Not Known is an error that occurs when a website or computer application is unable to connect to a server. This can happen due to an array of causes, from a broken DNS (Domain Name System) lookup to incorrect network configurations.
In this guide, we'll explain how this error can occur, how to troubleshoot it, and how to fix it. We'll also share some tips to keep this error from occurring in the future.
How Does "[errno -2] Name or Service Not Known"Error Occur?
This error occurs when the computer you are trying to connect to has an issue with its DNS lookup. The DNS is responsible for translating human-readable websites into IP addresses. If the DNS lookup fails, then the server the computer is trying to connect to won't be able to be found.
This can be due to a variety of causes, such as a broken DNS server, a corrupted DNS record, or incorrect network configurations.
Troubleshooting "[errno -2] Name or Service Not Known" Error
Once you encounter this error, the first thing to do is to figure out why it happened in the first place. You can do this by using your network's troubleshooting tools and checking for any potential problems with your network configuration.
You can also try to ping the server that you are trying to connect to and see if a response is received. If no response is received, then the problem may be on their end.
Fixing "[errno -2] Name or Service Not Known" Error
Once you have identified the problem and where it is coming from, you can begin to fix it. A number of steps you can take include:
Restarting the DNS service: If the error is coming from a broken or misconfigured DNS service, restarting that service can often fix the issue.
Flushing out the DNS cache: You can flush out the DNS cache either on your computer or your network router. Doing this can often resolve the issue.
Reconfiguring the network: If you are having problems connecting to a website, try resetting the configurations on your network and reconfiguring your network.
- Contacting the server: If the problem is on their end, try to contact the server you are trying to connect to and see if they can help resolve the issue.
