Why Does My Bottlepy App Throw a \'getaddrinfo failed\' Error?

Error Handling: Deciphering "getaddrinfo failed"

Encountering "getaddrinfo failed" when running the hello world sample from Bottlepy raises concerns about hostname resolution.

The error originates from the inability of the function getaddrinfo to resolve a hostname. This function is responsible for mapping a hostname to its corresponding IP address. When it fails, it means that the hostname provided cannot be recognized or translated into an IP address.

To rectify this issue, you can try replacing 'localhost' in this code snippet with '127.0.0.1':

<code class="python">import socket
socket.getaddrinfo('localhost', 8080)</code>

If the error persists, it indicates a broader problem with network configuration or hostname resolution. Ensure that your DNS settings are correct and that thehostname is resolving properly.

Ultimately, resolving "getaddrinfo failed" requires addressing the underlying problem with hostname resolution to establish a successful connection.
