OpenVidu is only available in https. So you need a certificate. Also, to avoid browser warnings, you will need a domain and a valid certificate. If you have a domain pointing to the IP then you can configure OpenVidu to create a valid certificate with Let’s Encrypt. Best regards ---

You have issues with your deployment. It seems the backend of OpenVidu Call is not properly deployed ![Screenshot_2021-11-20-08-30-37-509_com.android.chrome](https://global.discourse-cdn.com/free1/uploads/openvidu/original/2X/1/160f7181e701aa1a0b3d4c73f0af39fd4cc13b93.jpeg) ---

Hello , I have one more question to all of you. If I want to change whole UI of default openvidu then I have to change inside angular framework and build it. but Why I can not change in reactjs as I’m using below link for react js setup. [https://docs.openvidu.io/en/stable/tutorials/openvidu-library-react/](https://docs.openvidu.io/en/stable/tutorials/openvidu-library-react/) Please suggest me. ---

You can develop the UI with the framework you want. You just have to remove OpenVidu Call app from the deployment and deploy your own application. Regards ---

But I think we have to manage connect session, mute/unmute mic, hide/unhide video and other basic functions from scratch. so it may be difficult to find that. ---
