Error - 401 Unauthorized when calling Office 365 ECP Reportingwebservice

Question

Dear All, I am building a code to get Office 365 Message Trace. Before I using code from this source https://github.com/microsoft/o365rwsclient After a few changes this code works fine. But in April 1st, this code begin return 0 data. After some troubleshooting, I find out this code return 401 Unauthorized. In this code, I using basic authentication with my account. My account has Global Reading in my Tenant. Therefore I don't know if Microsoft retired Office 365 ECP ReportingWebService Rest API or because my account doesn't have enough permissions. Does anyone have any information or experience this problem?
