Getting Error 407 - Proxy Authentication Required. How Do I Fix This? or Error 407: Proxy Won't Let M

error 407 = you need proxy creds. If you’re at work, it’s not something you can skip.

Try this:
- Open cmd > type "netsh winhttp show proxy"
- If it shows a proxy, you’ll need the login from IT.

Bypassing it could violate company policy, so be careful.
