# Custom GPT action returns 401

A **ChatGPT** error and how to fix it. The exact message, why it happens, and the steps that resolve it.

ChatGPT

```
Error talking to connector: Unauthorized
Status: 401
```

 **Fix:**

Custom GPT actions don't read auth from the OpenAPI spec's `securitySchemes`. Configure it in the GPT builder:

1. Open the GPT → **Configure** tab → **Actions**
2. Click **Authentication** → pick API Key or OAuth
3. Paste the key and republish the GPT
