This catches aiohttp.ClientError and returns HTTPStatus<503> rather than HTTPStatus<500>.
We also catch the base aiohttp.ClientError rather than just aiohttp.ClientConnectorError, as for us, most client errors will also be TCP connection related, rather than actual invalid request data, etc and we include the exception information with the logged message, this can further aid debugging.
