The remote server returned an error: (407) Proxy Authentication Required

Hi,

I have completed the development of UiPath level 3 - Assignment 2 Generate Yearly Report for Vendors. But whenever I run the whole code it is working fine for 3-4 WIID and after it’s throwing error like Set transaction status: The remote server returned an error: (407) Proxy Authentication Required., and Get Transaction Item: The remote server returned an error: (407) Proxy Authentication Required..

Please help me to solve the issue ASAP.

Thanks,

Saili
