Based on the extracts provided, it seems like you're encountering an issue with retrieving an OAuth 2.0 login request in Ory Hydra. Unfortunately, the extracts do not directly address the specific error message "Failed to retrieve OAuth 2.0 login request" or provide a direct solution to this problem. However, to troubleshoot issues related to OAuth 2.0 login requests in Ory Hydra, you might want to consider the following general steps based on the information available: 1. Check for Misconfiguration: Issues with OAuth 2.0 flows, including the authorization code flow, often stem from misconfigurations. Review your setup to ensure everything is configured correctly. [Source](https://www.ory.sh/docs/hydra/debug#oauth-20-authorize-code-flow-fails) 2. Review Hydra Logs: For more specific error messages or hints about what might be going wrong, check the Hydra logs. These logs can provide more detailed information that can help in diagnosing the issue.

Authentication Operation: It's noted that the operation to get an OAuth2 login request does not require authentication. This might be relevant if the issue is related to how you're attempting to retrieve the login request. Ensure you're following the correct procedure that doesn't require user authentication at this step. [Source](https://www.ory.sh/docs/hydra/reference/api) If these steps do not resolve your issue, I recommend consulting the official Ory documentation or seeking support from the Ory community for more specific guidance related to your error. Unfortunately, without more detailed information or a direct reference to the error message you're encountering in the extracts provided, I can't offer a more specific solution.
