If you’ve deployed with AWS and you did not configured a domain name, you should use the domain name assigned to your instance by AWS. It is in the Cloudformation ![image](https://global.discourse-cdn.com/free1/uploads/openvidu/original/2X/0/0c5ae11ac20d2f2644aefe10a7ce18f5c1290298.png) Also, as you’re not using a FQDN your users should accept the certificate, if not it will not work. I recommend you to set up a domain name and use letsencrypt configuration [https://docs.openvidu.io/en/2.16.0/deployment/deploying-aws/#2-lets-encrypt-certificate](https://docs.openvidu.io/en/2.16.0/deployment/deploying-aws/#2-lets-encrypt-certificate) In this way you can use valid certificates. You just need a domain name Regards, Carlos ---

Please follow the steps described by @cruizba properly and use domain or subdomain name instead IP address Thanks Vipin
