Windows 10. Login and password are not requested in browsers when using http proxy. How to fix?

Question

Windows

Hello.
There is a corporate http proxy.
There are several Win 10 machines, not domain ones, where I use a proxy and everywhere in browsers when accessing a proxy, a login and password are requested, which is correct.
But on one Win10 machine, authorization is not requested. In the proxy logs I see a 407 error, which indicates that authorization was not passed.
There are no saved credentials in the control panel, I tried several browsers, all have the problem.
Can it be scored somewhere else? In the registry? Has anyone come across?

thanks in advance

Answer 1

Check the credentials in the "Control Panel - Credential Manager"
Perhaps once someone saved the name and login there to connect to the proxy.
