Fix BrowserConnectionClosedError
in Cypress
✅ Solution
BrowserConnectionClosedError typically occurs when Cypress loses its connection to the browser, often due to the browser crashing, becoming unresponsive, or external factors like a proxy interfering with communication. To fix this, ensure your browser is up-to-date and that no conflicting browser extensions or proxy configurations are interfering with Cypress's ability to control the browser. Restarting Cypress and the browser can also resolve transient connection issues.
