Error getting data from SaleseForce

[Anonymous]

Hi!

We use Qlik to have reports from SaleseForce. And now we have  some issue:

QVX_UNEXPECTED_END_OF_DATA: An existing connection was forcibly closed by the remote host

04/06/2018 08:20:09:           Error: Custom read failed

04/06/2018 08:20:16:           General Script Error

  04/06/2018 08:20:16:           Execution Failed

Connectin has parameters:

CUSTOM CONNECT TO "Provider=QvSalesforceConnector.exe;mode=SOAP;soapOption=SOAPQA;timeout=900;batchSize=2000 ....

This error was occured in different time and on different object.

What does it mean?

And what parameters can be responsible for this (Force, Qlik, etc.)?
