We're facing SSL Certificate issue in our Android & IOS browser. While SSL is working for -> Desktop browsers We're using domain [login to view URL] With port: 3000 Before without using port. It was working on android & IOS too. But after adding port its only not working in android & IOS browsers. So, we need to fix this issue. And it must use port 3000. Please don't add any proxies. We're using node JS & Sockets. so using proxy add delays in communication.
