Token exchange failed (HTTP {}): {body}

Error message

Token exchange failed (HTTP {}): {body}

What it means

The OAuth authorization-code exchange at OPENAI_TOKEN_URL returned a non-success HTTP status, so the code could not be redeemed for tokens. The status and body are included; typical causes are an expired/already-used authorization code, a PKCE verifier mismatch, or a redirect_uri mismatch.

Solutions

1. Restart the sign-in flow — authorization codes are single-use and expire within minutes
2. Check that the system clock is accurate; skewed clocks invalidate code exchange
3. Verify redirect_uri and client_id match those registered with the provider
