"Not logged in ? Please run /login" Claude Code error

Quick fix

Enable "API Proxy Takeover" in cc-switch when using hosted accounts like Copilot or Codex; direct upstream connections cause auth failures.

Symptom

Section titled “Symptom”
Error output
Not logged in ? Please run /login

Cause

Section titled “Cause”

Providers such as Copilot and Codex OAuth are hosted accounts that rely on cc-switch's local proxy for protocol conversion and Token management. If "API Proxy Takeover" is not enabled, cc-switch writes the upstream API address (e.g., https://api.githubcopilot.com) directly into the configuration file.

Since Claude Code cannot directly handle authentication and protocols from third-party platforms, direct requests result in authentication failures or model permission denied prompts. Additionally, calling the Copilot API directly without going through the proxy to merge tool calls and sub-agents causes session counts to be consumed abnormally fast.

Fix

Section titled “Fix”

  1. Enable the "API Proxy Takeover" feature in cc-switch to ensure the configuration file points to the local proxy address instead of directly to the upstream API.

    // ~/.claude/settings.json
    {
      "env": {
        "ANTHROPIC_BASE_URL": "http://127.0.0.1:15721",
        "ANTHROPIC_AUTH_TOKEN": "PROXY_MANAGED"
      }
    }

  2. Avoid using the "Open Terminal" function on provider cards to start providers requiring local routing; run the claude command via a regular terminal.

FAQ

Section titled “FAQ”
After enabling API Proxy Takeover, the model fields configured under the Copilot provider disappeared. Is this a bug?
No. After enabling proxy takeover, model configuration is managed uniformly by the proxy layer, so the direct upstream model fields are no longer retained in the configuration file.
Why does a simple conversation consume over a hundred call quotas after configuring Copilot?
Copilot bills per single conversation. If tool calls and sub-agent requests are not correctly merged via the proxy, each ToolCall is recorded as an independent session. Ensure you have enabled proxy takeover and are using a cc-switch version that has fixed this logic.
