**Hi @Veera_Ragavan ,**

Thank you for sharing the details of your issue. Here’s what I noticed based on your logs :

- The Pre-Registration Application Service is trying to connect to external modules such as **Masterdata, Authentication, IAM, and Configuration** , but these attempts result in failed connections or timeouts. This is because the URLs currently used in your setup (e.g., pointing to `dev.mosip.net` or `localhost`) are either inaccessible or incorrect for your setup.

**Why This Happens:**

- The issue occurs because the **Pre-Registration Application Service depends on external modules** (e.g., Masterdata, Authentication, IAM, Configuration) to function properly. Running the application locally without access to these services leads to startup failures—this is expected behavior.
- These necessary services are part of the **MOSIP ecosystem** and must be accessible for the Pre-Registration application to function as intended.

**What You Can Do :**

1. **If You’re Running the Application Locally :**

- Ensure you have access to the required services (Masterdata, Authentication, etc.), which are typically part of the full MOSIP setup.
- Refer to the **Deployment Getting Started Documentation** for guidance on setting up the MOSIP ecosystem.

1. **For Exploring the Application (Demo Mode) :**

- If your goal is to test how the application works, we recommend using the pre-deployed **Demo Environment** at `collab.mosip.net`.
- This environment is fully configured with all necessary services, allowing you to explore the application as intended without needing to set up your MOSIP ecosystem.
- Refer to the **Collab Pre-Registration Guide** for instructions on accessing and using this environment.

1. **For Exploring the Code :**

- If your objective is to understand the service or review the code structure :
  - Clone the Pre-Registration application’s codebase.
  - Build it locally to explore the logic and structure.

- **However** , running the application locally requires access to an environment where these dependent services are hosted and accessible.
  - If you have access to such an environment, update the `application.properties` file with the relevant service URLs (e.g., `spring.cloud.config.uri` and `mosip.base.url`).

Without access to these services, the application will fail to start successfully.

Let me know if this helps or if you need further clarification.

Best regards,  
_ **Team MOSIP** _
