Hey! Had the same issue last week. Turns out, my browser wasn’t passing the proxy credentials properly.
If you’re on Chrome, try this:
Go to *chrome://settings/* > Advanced > System > Open proxy settings.
From there, you can manually enter your proxy login details.
Also, check if your IT department gave you a specific proxy config file (.pac). Sometimes that’s the missing piece.
And yeah, http error 407 is a pain, but it’s just the proxy asking for a password nicely (or not so nicely lol).
