Hi After configuring my server to use **Let’s Encrypt** certificate. It working perfectly fine on Google Chrome desktop browser. But on android google chrome I have getting error. ![](https://global.discourse-cdn.com/letsencrypt/original/2X/f/f60a23b4ae2b1bf6945002d227fc27229b9d0183.jpg) Any reason why it’s not working? ---
