Hi @danthonyworks ,
Did you set your rules to use application default ?
Just wondering because I believe discord voice uses a big range of UDP ports for its media gateways. Check if the Service column is set to Any (or a custom service object covering UDP 50000-65535) or application-default.
I've also seen scenarios where we had to create an App Override rule for Discord to make it work. While generally not recommended because of security you might want to try it out for testing (How to create an application override)
Are the apps being identified correctly in the traffic log ? You mentioned changing QUIC timeouts. I've seen QUIC breaking things because it encrypts the headers that the firewall needs to see to identify the app. That said, when QUIC fails, apps like Discord (and Chrome/YouTube) should fall back to standard TLS/SSL and UDP, which the firewall can inspect and allow much more reliably.
Kind regards,
