When it comes to music streaming, Spotify is always on the top of the list. It has been one of the most reliable brands in playing music online and continues to provide its users with satisfying features and functions.
However, there are times when you encounter issues that prevent you from opening and using your Spotify app. You may see the error message, “A firewall may be blocking Spotify. Please update your firewall to allow Spotify. Additionally you could try changing the currently used proxy settings. Error code: 30”

In some cases, the error code Auth:3 or 117 appears instead of the error code 30. The firewall or proxy server on your Windows 10 PC or Mac computer does not provide permission for the Spotify app or website to operate so you can get access to your songs, podcasts, and playlists. You can try to troubleshoot and resolve this issue by following some of the methods below.
