Hello, I have install docker and pull your app and run it … after that i have tried to create certification by this code : openssl req -newkey rsa:2048 -new -nodes -x509 -days 3650 -subj ‘[//CN=192.168.99.100](https://CN=192.168.99.100)\O=My Company LTD.\C=US’ -keyout key.pem -out cert.pem then i used this code to rund certification : http-server -S gave me this : Available on: [https://10.0.75.1:8080](https://10.0.75.1:8080) [https://192.168.1.19:8080](https://192.168.1.19:8080) [https://127.0.0.1:8080](https://127.0.0.1:8080) [https://172.29.124.129:8080](https://172.29.124.129:8080) [https://172.28.80.1:8080](https://172.28.80.1:8080) Hit CTRL-C to stop the server but the camera and microphone not work and you can see attachment to be the problem clear ![Untitled](https://global.discourse-cdn.com/free1/uploads/openvidu/original/1X/687db137500cd7650330ed0a804acfba03fc441c.png) ![Untitled](https://global.discourse-cdn.com/free1/uploads/openvidu/original/1X/9bb27168f938fa582a3ec770129488f5b823f694.png) ---

Seems to me your browser cannot establish a connection to 192.168.99.100. That’s definitely a networking problem. Please, try serving your OpenVidu Server instance at a reachable IP for your browser.
