Browser randomly closing and starting again

[Nikola-Milovic]

Hello, I am building a crawler with go-rod and I want to have a clear state for every request. The easiest solution I found was to create an incognito browser instance every time

func (c *crawler) Clean(ctx context.Context) error {
	if err := c.browser.Close(); err != nil {
		return fmt.Errorf("failed to close browser: %w", err)
	}

	newBrowser, err := c.parentBrowser.Incognito()
	if err != nil {
		return fmt.Errorf("failed to create incognito browser: %w", err)
	}

	c.browser = newBrowser

	return nil
}

parentBrowser is the actual browser instance
browser is the browser we're using for the actual crawling

This cleaning isn't happening too often. But I started experiencing connectivity issues when adding this functionality

failed to get page, cause: write tcp 192.168.155.12:3000->192.168.155.18:7317: use of closed network connection

1. Could this be related? Or is this some unfortunate timing of infrastructure issues? My suspicion was that the browser might not be initialized or some weird caching is happening, but that doesn't seem to be case as every follow-up request works fine
2. For every instance of crawler I spin up a new browser via a ManagedLauncher but from the docs for TargetCreateBrowserContext (experimental) it states Creates a new empty BrowserContext. Similar to an incognito profile but you can have more than one., so basically I can use a single browser instance and create new Incognito browsers from it, and they'll all be independent from each-other in terms of cache, cookies and such?
