Browser close reasons
A browser session may close for a variety of reasons, occasionally due to connection errors or errors in the headless browser instance. As a best practice, wrap puppeteer.connect or puppeteer.launch in a try/catch ↗ statement.
To find the reason that a browser closed:
- 
In the Cloudflare dashboard, go to the Browser Rendering page. Go to Browser Rendering
- 
Select the Logs tab. 
Browser Rendering sessions are billed based on usage. We do not charge for sessions that error due to underlying Browser Rendering infrastructure.
| Reasons a session may end | 
|---|
| User opens and closes browser normally. | 
| Browser is idle for 60 seconds. | 
| Chromium instance crashes. | 
| Error connecting with the client, server, or Worker. | 
| Browser session is evicted. |
