... API

Client is trying to retrieve prices using the following API: #DataScope.Select.Api.Extractions.ExtractionRequests.IntradayPricingExtractionRequest

Because of the number of prices to retrieve it is split up in multiple requests (each time for 1000 instruments).So for each 1000 instruments he does the REST API call and then process them and wait for 30 seconds and do the following call.

In production client saw in the log file that 4 batches are processed OK, but with the fifth batch the HTTP socket was closed. This situation reoccured the next day. Can you please advise what could be the cause?

    I checked the log and found the connection has been closed while retrieving a response.

    I tested the request message with Postman and Postman can show the response properly.

    Does the client has a proxy or firewall server?

    The client can share the runnable source code so I can test it in my environment.
