How can I diagnose a 'recaptcha error' in a browser?

To diagnose a recaptcha error in a browser, first check the browser's developer console (usually accessed by pressing F12). Look for error messages related to Recaptcha. The console will often provide more specific error details than the Recaptcha error code. Also, examine the network requests to see if Recaptcha is failing to load correctly. Browser extensions that block scripts or ad trackers might interfere with Recaptcha's functionality. Disable extensions temporarily to see if that resolves the issue. Finally, clear your browser cache and cookies.
