How to fix timeout error

Hi there,

I attempted to export the data from the Splunk backend through the REST activity of ADF. REST API. However, I received the following error.

Are there any other options for the earliest and latest times listed below? Can it be precise to the hour?

earliest=-155d
latest_time=-154d
output_mode=json
time_format=%25Y-%25m-%25d+%25H%3a%25M%3a%25S
max_count=50000000

Failure happened on 'Source' side. ErrorCode=RestResourceReadFailed,'Type=Microsoft.DataTransfer.Common.Shared.HybridDeliveryException,Message=Fail to read from REST resource.,Source=Microsoft.DataTransfer.ClientLibrary,''Type=System.IO.IOException,Message=The read operation failed, see inner exception.,Source=System.Net.Http,''Type=System.Net.WebException,Message=The operation has timed out.,Source=System,'

Thanks & Regards, zmsoft
