Fix cURL Domain Resolution in C++

If cURL encounters difficulties in resolving domain names, it could be due to network configuration issues or problems with the cURL library itself. Here are some possible solutions:

1. Make sure the internet connection is working properly: First ensure that your computer is able to connect to the internet and there are no network configuration issues.
2. Check DNS settings: Verify if the DNS settings on your computer are correct, you can try using a different network connection to see if the issue still persists.
3. Update the cURL library: If you are using an older version of the cURL library, try updating to the latest version to see if the issue has been fixed.
4. Check firewall and proxy settings: Make sure your firewall or proxy settings are not blocking cURL from connecting to the domain.
5. Try connecting using the target server’s IP address instead of the domain name to see if the issue is resolved.

If the above method does not work, further investigation into the root cause of the issue may be necessary. You can try testing in different environments and consult the cURL library documentation for more information.
