Has the browser been updated? What's the version of the browser? Can you try this site to see if it works with your browser - https://cagdemo.com?

Hi VVasco,

This CORS issue with BrowserPrint SDK can be frustrating. Here are some potential solutions:

1. Check BrowserPrint Service configuration:

{
   "AllowedOrigins": ["https://mysite.it"],
   "EnableCORS": true
}

2. Verify your browser's security settings:

• Make sure you're using the latest version of BrowserPrint
• Clear browser cache and cookies
• Try in incognito mode

3. Server-side solutions:

// Add these headers to your server response
res.header('Access-Control-Allow-Origin', 'https://mysite.it');
res.header('Access-Control-Allow-Headers', 'Origin, X-Requested-With, Content-Type, Accept');

4. Check if your site's SSL certificate is valid and up-to-date
5. Try updating the BrowserPrint Service to the latest version

If none of these work, you might want to:

• Check Windows Firewall settings
• Verify that port 9100 is not blocked
• Review any recent browser updates that might affect CORS policies
