OpenVidu Platform configuration is specified in the .env file with environment variables. You must give a value to properties DOMAIN_OR_PUBLIC_IP and OPENVIDU_SECRET. Default empty values will fail. Therefore, you can change the CERTIFICATE_TYPE if you have a valid domain name.

Or if for any unknown reason you prefer to use your own certificate, set the property to owncert and place the certificate files as explained.
