We were doing some SharePoint list operation using a console application using visual studio 2015. But while running the code we got the below exception in the ExecuteQuery method which says:
An unhandled exception of type ‘System.Net.WebException’ occurred in Systme.dll.
Additional information: The remote server returned an error: (407) Proxy Authentication Required. The full error looks like below:
The remote server returned an error 407 Proxy Authentication Required
To resolve the issue we have changed the proxy settings like below:

- Check Automatically detect settings
- Uncheck Use automatic configuration script
- Uncheck Use a proxy server for your LAN (These settings will not apply to dial-up or VPN connections).
