@Michael22105 ...
I'm assuming that you are using the Re-direct app because you want this particular page to be something students will go back to multiple times during your course. Is that correct? If so, I can see the value in doing something like this. However, if you are getting an error message like you are seeing, I wonder if it's just easier for you to make a module at the top of your "Modules" page and call it something like "IMPORTANT INFORMATION" (or whatever you want to call it), and then you can just add that published page to the module. Then, keep the module at the top of the "Modules" page (above all your other modules) so that when your students are completing their course work, it's the first thing they always see.
Another option for you (which you might already have in your course) is a front page with some buttons to different areas of your course. One of these buttons could point to the page that you are wanting your students to see.
Again, I'm making a lot of assumptions here, so please feel free to add any other details that might help...thanks!
