  • Claude Code version: 2.1.195
  • OS: Ubuntu Linux VPS (SSH headless)
  • Account: Claude Pro (active, confirmed at claude.ai/settings)
  • Login method: Google OAuth

Error: "Redirect URI https://platform.claude.com/oauth/callback is not supported by client"

All /login attempts fail with this error regardless of version (tested 2.1.108 and 2.1.195).
Previously worked fine before subscription expired and was renewed.
