You should use a valid certificate. For that, you will need to purchase a domain.

If you do not have a domain, your users will have to accept the invalid certificate (dangerous) before connecting to video conference.

That’s because you’re not using a domain, you’re using an IP. Your users need to accept this certificate. There is no other solution. Just open [https://3.128.109.91](https://3.128.109.91) in a browser and accept the certificate
