Description

Attempting to listen to listen to this interview. Playable in browser, but cannot extract link, which is not paywalled and no credentials are required. Returns 403 Forbidden error. I attempted from multiple VPN servers to rule out that possibility, and also built the latest version from GitHub, same error returned. Thanks!
