**Description** 1. Firstly, my browser is giving CORS error even when I added PHP header 2. So I disabled CORS for sometime and again tried to connect but time, worst happened. Your certificate is invalid and so basically Chrome is declining connection. I disabled Kaspersky Antivirus but the problem is not solved. Please check it from your end. ![Screenshot (189)](https://us1.discourse-cdn.com/flex016/uploads/zoomdeveloper/original/2X/1/13afea83650181e64efcafc9f7ee3b03c19b3e3a.png) ---
