How do you update firewall to allow Spotify?

To update your firewall to allow Spotify, first, access your firewall settings through your operating system or firewall software. Look for an option to add exceptions or rules, then create a new rule that allows outbound connections for Spotify's executable file (usually located in the program files) and any associated ports (such as TCP port 443). Finally, save the changes and restart the firewall if necessary to ensure the new rules take effect.
