It’s ubuntu 20.04 version and I installed docker. The sequence is as follows. 1. sudo su 2. cd /opt 3. curl [https://s3-eu-west-1.amazonaws.com/aws.openvidu.io/install\_openvidu\_latest.sh](https://s3-eu-west-1.amazonaws.com/aws.openvidu.io/install_openvidu_latest.sh) | bash 4. cd openvidu 5. nano .env 6. My .env file Setting DOMAIN\_OR\_PUBLIC\_IP=220.89.167.212 OPENVIDU\_SECRET=MY\_SECRET CERTIFICATE\_TYPE=selfsigned HTTP\_PORT=4443 HTTPS\_PORT=4443 7. .env file save completed. 8. ./openvidu start start completed. * * * ## OpenVidu Platform is ready! - OpenVidu Server: [https://220.89.167.212:4443/](https://220.89.167.212:4443/) - OpenVidu Dashboard: [https://220.89.167.212:4443/dashboard/](https://220.89.167.212:4443/dashboard/) * * * If you connect to the server address, the connection is not possible. What’s wrong? ---

Why have you set HTTP and HTTPS ports to the same port number? That will bring problems, for sure. Remove your HTTP\_PORT=4443 declaration. Use only HTTPS\_PORT. ---

I removed the HTTP\_PORT=4443 entry, but it still doesn’t work. Is there anything else you can check? ---

But what is the error you get in the browser? Check the logs of other containers running, like nginx: ```auto sudo su cd /opt/openvidu docker-compose logs nginx ``` Also check your opened ports: [On premises - OpenVidu Docs](https://docs.openvidu.io/en/2.21.0/deployment/ce/on-premises/#1-prerequisites) ---

Browser error is ‘Connection denied.’ The log can be checked tomorrow. ---

Ok, check the log for any error tomorrow and come back. Regards, Carlos ---

Looks ok. Can you do a `docker ps`? Did you check all your ports are reachable?
