HTTP request error 407: proxy authentication required

How to Enable Authenticated Proxy with the Logged in User in UiPath.

To Redirect the Robots using the Proxy below configuration needs to be configured. 
Redirecting Robots through a Proxy Server

However in case the Proxy server that you have needs Authentication, useDefaultCredentials parameter needs to be used which will use make the Request to Proxy server via Default Credentials of the logged in user.
 <defaultProxy useDefaultCredentials=“true”>

Please note, currently UiPath does not support configurations where you need to make request to Proxy server with specific user. This is not yet supported. 

Thanks. This was helpful.

Unfortunately, this isn’t working for version 2021.4.1 and above, because the proxy.config file is no longer in the app folder. Please kindly advise any workaround. Thanks
