honestly, you should know what you are trying to achieve without using hyperboles! then find out if what you are trying to achieve will actually work. You’re using “Docker on Unraid” and you are obviously trying to host Nextcloud locally without a public DNS and valid certificate! That’s definitely not what Nextcloud was designed for.

you need a domain name with a valid certificate see 101: Network, domain and DNS
