API - Getting the status of a stats request results in failed without any other explanation

I am attempting to get calls using the https://dialpad.com/api/v2/stats post method to generate a report and then using the https://dialpad.com/api/v2/stats/ to get the status of the report with the download link. Sometimes it works and other times it doesn't. The code that is running is exactly the same each time. When it doesn't work all I get is a status of failed. Is there something else that I can query to see why it failed or why would it fail? Thanks in advance
