We have a daily schedule to do DSS API calls (a series of calls like get schedule id, report extraction id, get report data etc.) to fetch market rates. I am getting the below exception when performing these calls:
io.micronaut.http.client.exceptions.HttpClientResponseException: <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN""http://www.w3.org/TR/html4/strict.dtd">
<META HTTP-EQUIV="Content-Type" Content="text/html; charset=us-ascii"></HEAD>
<hr><p>HTTP Error 503. The service is unavailable.</p>
This is not happening everyday. In a month I observed it only twice. But when retried in few minutes, the calls work. Could anyone tell me why this could be happening?
It could be a problem on the DSS server or a proxy (if you have one).
You can contact the DSS support team directly via MyRefinitiv to verify the problem. Please provide them with the time when the problem occurred and the request message and URL that cause this error.
