You didn't tell us what you do to get this, so the only thing we can talk
about is HTTP response code 503. It is documentedin RFC 7231 section 6.6.4 and
says:
The 503 (Service Unavailable) status code indicates that the server
is currently unable to handle the request due to a temporary overload
or scheduled maintenance, which will likely be alleviated after some
delay. The server MAY send a Retry-After header field
(Section 7.1.3) to suggest an appropriate amount of time for the
client to wait before retrying the request.
Like all 5xx codes, the "fault" here is in the server. It is not caused by the
client - assuming it returns a correct response code.
