socket_connect(): Host lookup failed [-10000]

This error message is indicating that the program was unable to lookup the IP address for the host you are trying to connect to. This could be due to a variety of reasons, such as a network issue, DNS resolution issue or the host being down.

To resolve the issue, you can try the following steps:

1. Check your internet connection: Make sure that your device is connected to the internet and that there are no connectivity issues.

2. Verify the hostname: Double-check that the hostname or IP address you are trying to connect to is correct.

3. Check DNS settings: If you are using a DNS server to resolve hostnames, make sure that the DNS settings are configured correctly. You can try changing the DNS server settings to see if that resolves the issue.

4. Try a different port: If you are connecting to a specific port, try using a different port to see if that resolves the issue.

5. Contact the administrator: If none of the above steps work, the host you are trying to connect to may be down or experiencing issues. Contact the administrator of the host to see if there are any issues on their end.
