TYPO3 Questions Installation

Hello,

TYPO3 Version 10.4.31

The Problem with “preconfigured distribution”.

“The Official TYPO3 Introduction Package” - works.

With another packages I became:

“The requested URL /[Subfolder]/[TemplateName]was not found on this server.”

But under “https://SERVERNAME/[Subfolder]” - I get the Installation-Startsite.

And I can to Install new instaces of Template.

I thought somethign wrong with Full Url Prefix , but I cant get it works.

How can I get Instance of Template for Preview?

Thanks
