Status Code 001 In Logs

[abstein2]

Sorry for the delay. I do think part of the issue is tied to the load
balancer since that connection is timing out (we set it very low for testing
purposes), but the load balancer terminating the connection doesn't explain
why nginx is returning a 001 status code, since the connection from the
nginx box to the origin box shouldn't be affected by that.

nginx -V:
