  +Use this table when you are debugging Gorouter errors.
  +The table lists error types, status codes, and indicates if the Gorouter retries the errored request.
  +
  +For each error, there is a `backend-endpoint-failure` log entry in `gorouter.log`
   and an error message in `gorouter.err.log`.
   Additionally, the `access.log` records the request status codes.
   For more information, see the [Gorouter documentation](https://github.com/cloudfoundry/gorouter#logs) on GitHub.
   
  -If the Gorouter encounters an error that is not one of the classified errors,
  -then a <code>502</code> status code is the default response.
  -Gorouter tracks `502` errors with the `gorouter.bad_gateways` metric.
  -For more information, see [Router Error: 502 Bad Gateway](<%= vars.gorouter_metrics_link %>).
  -
  -If the error type is re-tryable, Gorouter tries the operation up to three times.
  +If the request is one that can be retried, Gorouter makes up to three attempts.
