Think this is the one: 0c2a690cc6c0
I can see that at 2017/07/20 09:22Z it connected directly, but previously it had been attempting to connect via a proxy (104.x.x.x). Looks like the proxy was not responding to auth - we sent login details but never got a response, so never managed to connect through to the servers.
