Hi, I just purchased OpenVidu and wanted to deploy it on my linux server. I downloaded and configured docker file. When i start OpenVidu by `./openvidu start` it gives the following log > openvidu-server\_1 | [INFO] 2020-05-11 10:12:25,021 [main] io.openvidu.server.core.SessionManager - Garbage collector for non > active sessions initialized.

My server has nginx installation. I tried to start OpenVidu by stopped the nginx server on my linux but still no luck. Can you tell me what am I missing? Best ---

OpenVidu installation procedures are designed to be installed in an empty machine because it needs several available ports in the machine: We recently add some information to our documentation regarding to this: > **Free ports inside the server** : OpenVidu Server Pro Node services will need the following ports to be available inside the machine: 80, 443, 3478, 5442, 5443, 6379. If some of these ports is used by any process, OpenVidu platform won’t work correctly. It is a typical error to have an NGINX process in the system before installing OpenVidu. Please uninstall it. If you still need to use your own NGINX in the machine, wait until 2.14 release (to be published tomorrow) to be able to change OpenVidu NGINX ports (80 and 443). Can you stop other services and try again and share with us all openvidu services logs to see what is wrong? Regards ---

Hi @ertan, The NGINX is not capable of using port 80, and it does not get a certificate using letsencrypt. Please try the following: 1.- Turn off your local nginx with the command `sudo systemctl stop nginx` 2.- Delete the contents of the “certificates” folder with the command `rm -rf /opt/openvidu/certificates/*` 3.- Restart Openvidu, first go to the `cd /opt/openvidu` folder and then run `./openvidu restart` Greetings ---

Hi @ertan, The NGINX not working correctly because fails getting letsencrypt certificated. You need configure properly a email in the ‘LETSENCRYPT\_EMAIL’ variable. Nonetheless try deploy with “CERTIFICATE\_TYPE=selfsigned” mode. Regards ---
