Getting HTTP 407 Proxy Authentication Required – How to Fix It? or Why Am I Seeing HTTP 407 and How D

Your work proxy might’ve switched to NTLM or Kerberos auth. If you’re on Windows, run `gpupdate /force` to sync group policies.

Or, if you’re feeling brave, manually tweak the registry (Google "proxy auth registry fix"). But fair warning: IT might side-eye you for that.
