I am assuming it hasn't been configured correctly on attack, but currently it's returning a nasty server crash.

1. That looks more like a 400 rather than a 404?
2. Can we still replicate this issue?

[sebastian]

You are right! I updated the title. I have no idea how to replicate this.

We are now logging an error instead: https://github.com/Aircloak/aircloak/commit/7500e3ab08f8e8a1e318116c62325cc40baf3941
