Community Document Server Help Needed

Hi

I just installed Nextcloud and am having issues with community document server. I see a lot of people have the same issue as me saying that it is unavailble in this instance, when I tick the box saying use demo, it works so thats a temporary fix at least.

I try to update to 0.1.5 but everytime I do maintenance mode gets enabled and the server times out, I cant find the php.ini file to edit the timeout time either.

Thanks in advance.

So now when I enter what i believe to be my DESA it times out and im not sure how to stop it timing out, see screenshot
