Missing Update button and 404 / private error on /admin/upgrade

Hi everyone,

I am trying to update my Discourse instance from the web interface, but I cannot find the Update button anywhere on my Admin Dashboard.

When I try to navigate directly to the upgrade URL (/admin/upgrade), I get the following error:

Oops! That page doesn’t exist or is private.

I am logged in as an administrator.

Has the web update button been moved or removed in recent versions, or is there a specific setting configuration required to enable it?

Any guidance on what to check would be appreciated!

How did you install Discourse?

I install it normally on my server using Docker

Does your app.yml file contains the docker-manager plugin?
