Based on the information provided in the knowledge sources, there are a few potential reasons why you might be encountering a 403 Forbidden error when trying to access

<http://127.0.0.1:4000/.ory/login>

using Ory Proxy. Let's explore some possible issues and solutions: 1. Inconsistent use of localhost and 127.0.0.1: The documentation emphasizes using either

localhost

or

127.0.0.1

consistently, but not both. As mentioned in the [React integration guide](https://www.ory.sh/docs/getting-started/integrate-auth/react#run-ory-apis-on-localhost): > When developing locally, use either

localhost

or

127.0.0.1

, but not both. Although technically these mean the same thing, they're different hostnames. Ensure you're using the same hostname throughout your configuration and access attempts. 2. Incorrect Ory Proxy configuration: Make sure you've correctly set up Ory Proxy. The [Ory Proxy documentation](https://www.ory.sh/docs/guides/cli/proxy-and-tunnel#use-ory-proxy-for-local-development) provides an example command:

ory proxy --project <project-id> --workspace <workspace-id> <http://localhost:3000>

Ensure you've used the correct project ID and workspace ID in your command. 3. CORS (Cross-Origin Resource Sharing) issues: The error might be related to CORS. As mentioned in the [debug section](https://www.ory.sh/docs/kratos/bring-your-own-ui/custom-ui-basic-integration#debug): > Ory has a "deny by default" policy which means that the

Access-Control-Allow-Origin

header is just set on domains owned by Ory. To resolve this, you can use Ory Tunnel for local development or add your domain to the Ory Project for production use. 4. Incorrect port usage: By default, Ory Proxy listens on port 4000. If you've changed this, make sure you're using the correct port in your URL. You can specify a different port using the

--port

flag as shown in the [Ory Proxy documentation](https://www.ory.sh/docs/cli/ory-proxy#ports):

ory proxy --port 8080 --project <project-id-or-slug> <http://localhost:3000>

5. Misconfigured local development setup: Ensure you've properly set up your local development environment as described in the [local development guide](https://www.ory.sh/docs/getting-started/local-development#local-development). This includes using Ory CLI Tunnel:

ory tunnel --dev --project $PROJECT_SLUG <http://localhost:3000>

If none of these solutions resolve your issue, you may need to check your specific Django configuration and ensure it's correctly integrated with Ory. If the problem persists, you might want to review the Ory documentation for any Django-specific instructions or reach out to Ory support for further assistance.
