Based on the information provided in the extracts, there could be a few reasons why Ory Kratos is not redirecting after a successful login. Here are some things you can check: 1. Same Top-Level Domain: Ory Kratos and your UI must be hosted on the same top-level domain. For example,

<http://kratos.bar.com|kratos.bar.com>

and

<http://ui.bar.com|ui.bar.com>

will work, but

<http://kratos.bar.com|kratos.bar.com>

and

<http://not-ar.com|not-ar.com>

will not work. [source](https://www.ory.sh/docs/kratos/self-service/flows/user-login) 2. Login Flow Initialization: Make sure you have correctly initialized the Login Flow. This involves pointing the browser to the initialization endpoint. [source](https://www.ory.sh/docs/kratos/self-service/flows/user-login) 3. Login URL Configuration: Check if you have correctly configured the login URL in the Ory Identities config. [source](https://www.ory.sh/docs/kratos/self-service/flows/user-login) 4. Session Cookie: On successful login, Ory sets the CSRF cookie and issues a session cookie that can be used to authenticate subsequent requests to Ory. Make sure this is happening correctly. [source](https://www.ory.sh/docs/kratos/bring-your-own-ui/custom-ui-basic-integration) 5. Login Methods: Ensure that the login methods (

password

or

oidc

) are enabled in the Ory Identities configuration. [source](https://www.ory.sh/docs/kratos/self-service/flows/user-login) If you've checked all of these and are still experiencing issues, you may want to refer to the Ory Kratos documentation for more detailed troubleshooting steps.

Integrating a self-hosted Ory Kratos as the login service for your self-hosted Ory Hydra involves several steps. Here's a general flow based on the information provided in the extracts: 1. Initialize Login Flow: Before any data can be sent to Ory, a flow must be initialized. You can create a flow by sending a GET request to the

/self-service/{flow_type}/{browser/api}

endpoint. For example, to initialize a login flow for a browser application, you would use the following command:

bash curl -X GET \    -H 'Content-Type: application/json' \    -H 'Accept: application/json' \    -c cookies.txt \    https://{project.slug}.<http://projects.oryapis.com/self-service/login/browser|projects.oryapis.com/self-service/login/browser>

[source](https://www.ory.sh/docs/kratos/bring-your-own-ui/custom-ui-basic-integration) 2. Submit Login Flow: After initializing the login flow, you can submit the flow by sending a POST request to the Ory project URL. For a server-side rendered browser application, the submission is handled by a native form POST to the Ory project URL. For example, login is a POST request to

https://{project.slug}.<http://projects.oryapis.com/self-service/login/browser?flow=<id>|projects.oryapis.com/self-service/login/browser?flow=<id>>

. [source](https://www.ory.sh/docs/kratos/bring-your-own-ui/custom-ui-basic-integration) 3. Configure Ory to Use Your UI: To define the paths where Ory calls your custom UI, go to Ory Console → User Interface. This view allows you to define the URLs of UI views for every self-service flow. To point to the desired UI, you can use relative or absolute paths. [source](https://www.ory.sh/docs/kratos/bring-your-own-ui/configure-ory-to-use-your-ui) 4. Integrate with Ory Hydra: After setting up Ory Kratos, you can integrate it with Ory Hydra. You can fork the Ory Hydra Node.js UI Reference or build a custom UI in the language of your choice. You can then add Identity and Account Management to your application. [source](https://www.ory.sh/docs/hydra/self-hosted/deploy-hydra-example) Please note that the exact flow and APIs to call may vary depending on your specific setup and requirements. For more detailed instructions, you may want to refer to the Ory Kratos and Ory Hydra documentation.
