Hey Andrew,

So unless there's some awkward parsing, this 503 is not the error code in this case. I don't have custom log configurations, so I'm sitting here assuming that the -1 is where the status code ought to be. 5 positions of timing sperated by a '/', all of which look kinda legit considering the termination state. Followed by a status code, in my case -1, followed by 'bytes read', in my case 503. And the CDNN is actually two errors CD and NN CD The client unexpectedly aborted during data transfer. This can be caused by a browser crash, by an intermediate equipment between the client and haproxy which decided to actively break the connection, by network routing issues between the client and haproxy, or by a keep-alive session between the server and the client terminated first by the client. NN No cookie was provided by the client, none was inserted in the response. For instance, this can be in insert mode with "postonly" set on a GET request. More information could be provided with a valid configuration I hope this helps?

We are getting a status code of -1. The status CDNN is odd enough as it is… Why would this be?
