Nexcloud server Installation

Hi All, I could able to install the apache reverse proxy method to install the nextcloud-aio.

This may be due to the network design. We have a public and private dns with the same name. The request will come from the public dns → private dns.

If I use only privite dns entry, I could get the login page but when I am having the public → private setup, It is giving the above error.

Can someone help me if there are any further configuration changes fix my issue here.

I have gone through few topics like this but unable to fix my issue. Nextcloud AIO Install: location of the backup archive
