Ubuntu LEMP 16.04

I can’t for the life of me figure this out. I’m trying to redirect a .zip file to a page on a new domain. I tried using the htaccess file but It doesn’t seem to be working.

The Idea Is to get

111.111.11.11/myold.zip

To redirect to a page on my actual site

https://newdomainpage.com/sample-page

My latest attempt

<IfModule mod_rewrite.c>
//301 Redirect Old File
Redirect 301 /myold.zip https://newdomainpage.com/sample-page
RewriteRule /myold.zip)$ https://newdomainpage.com/sample-page$1 [R=301,NC,L]
</IfModule>

Am I missing something, or Is this not possible?

Stash
