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 Run page.
Go to Browser Run -
Select the Runs tab.
Browser Run sessions are billed based on usage. We do not charge for sessions that error due to underlying Browser Run 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. |
