Next and previous buttons dont work

I am trying to create a blog on a seperate page of my site. for example I have a page called blog. and then a category for all the blogposts I want to display there, but when I click the next/previous buttons it simply just displays the same posts. I think it’s because it’s trying to locate the posts through the page rather than the category. Though it is also not working on the blog’s category either.

Any help appreciated thanks!
