Getting 407 Proxy authentication required while using Auth0 winforms

Hi ,

I am using Auth0 winform desktop application to connect to our cloud application. Sometimes it is throwing “407 - Proxy authentication required” error while trying to login using client.LoginAsync() method.

while getting this error , if I load my cloud application in browser and login there , and then reload this desktop application again , now it works without throwing any error .

I don’t know how desktop login application is connected with browser page . Can anyone please help me with this issue .
