# Troubleshooting "Failed to validate certificate" error when launching IGV BaseSpace Application

Java will attempt to verify the Integrative Genomics Viewer (IGV) application prior to launching and can fail with the following error message:

![](/files/YiRaLq65pHYJg4IjQuSs)

Installing or Upgrading Java from the link provided on the IGV app page will not resolve the issue. Follow the workaround instructions below to circumvent this error message and launch the IGV app on BaseSpace.

**Add application URL to Java exception list :**

1. Go to the **Control Panel** from the Start menu.
2. Double-click on the **Java icon** to get the Java control panel dialog box.
3. Navigate to the **Security Tab**.
4. Click the '**Edit Site List**' button.
5. Click the **Add** button in the Exception Site List window.
6. Click in the empty field under **Location field** to enter this URL: [https://basespace-launch-east.s3.amazonaws.com](https://basespace-launch-east.s3.amazonaws.com/)
7. Click the **OK** button.
8. Go back to the Java Control Panel under the **Advanced tab**.

* There is a setting, “Perform signed code certificate revocation checks on”, which can be changed by clicking on “Do not check (not recommended)”. That will disable the revocation check and allow end users to log into the application.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://knowledge.illumina.com/software/cloud-software/software-cloud-software-troubleshooting-list/000007890.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
