ZenArmor blocks thunderbird.net

ZenArmor is configured to block QUIC. Now, thunderbird.net is somehow blocked even via TCP.

```

curl -vvv https://thunderbird.net

curl -vvv http://thunderbird.net

```

Both get blocked. In the panel, we can see that the protocol is TCP - but somehow, the application protocol is detected as UDP (how does that even make sense? UDP isn't an application layer protocol).

Interestingly, `curl -vvv http://thunderbird.net:443` (note the https port over http) *does* go through, and is detected as TCP + Generic TCP instead.

This seems like a bug in ZenArmor, can anyone reproduce this?
