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.

The reason that a browser closed can be found on the Browser Rendering Dashboard in the logs tab ↗. When Cloudflare begins charging for the Browser Rendering API, we will not charge when errors are 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.
