Alter this code to make it work for logging into and downloading a report from Seller Central -- 2

The below code used to work by logging into Amazon seller central, requesting for a report, waiting for the report to be completed and then finally downloading it. However, past 1 week, it doesnt seem to be working as it doesnt get past the login step. Once login works after the fix, you would also need to check the rest of the steps so that finally the stranded inventory report gets downloaded from Amazon Seller Central. The scope of this project would be to rectify this code so that it works exactly as before. All credentials and exiting source code will be provided. This is a quick and small project and would really appreciate a turnaround of 1 day for this Attachment has the code with all necessary URLs.
