Hello, there are two options to solve your issue. The underlying issue is safari does not allow mixed content. By mixed I mean http and https together on the same page. On solution is to use the http version of your stack just replace the stackname with your stackname from your dashboard: http://dev-01.q2developer.com/sdk//ardent/uux.aspx#/login This can be a bit tricky as the browser likes to force you to use https. So you need to make sure it is actually loading in http. I normally solve this by using incognito windows.

The other option is to bind a certificate to your react app via the following guide.
