# YouTube Login Has Expired
{% hint style="danger" %}
Your login session has expired, so the broadcast cannot be started. Please try logging in again.
{% endhint %}
This guide explains the cause of the current error that occurred during your live streaming.
***
To stream to YouTube, the PRISM app relies on features provided by YouTube. These features are known as YouTube Open APIs, which are used by third-party apps like PRISM.
To use these APIs, the PRISM app requires your YouTube login information. Through the login process, PRISM obtains the necessary permissions to access YouTube’s API services.
However, your current login session has expired, which means the PRISM app can no longer access YouTube’s features. As a result, your live stream could not be started.
To resolve this issue, please log in to your YouTube account again. Once you’ve successfully logged in, try starting the live stream again.

## 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 following URL with the `ask` and `goal` query parameters:
```
GET https://guide.prismlive.com/mobile/guides/error-solution/youtube/youtube-login-has-expired.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `build a script that syncs our docs to a CMS` lets GitBook tailor the answer to that use case.
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.
