Publish-AzWebApp : One or more errors occurred. System.Net.WebException: The remote server returned an error: (502) Bad Gateway

Question

I am trying to publish the code via zip deployment using powershell (Please note that I can only use powershell in my system). When I deploy, I get the following error: Publish-AzWebApp : One or more errors occurred.
