Categories don't go to page 2!

Hi!
The thing is: my category goes to first page but not a second one, and it has posts to do it! Instead it goes 404
an example:
https://caminhod.com.br/category/descolhas/page/2/ -> goes 404
https://caminhod.com.br/category/descolhas/ -> nromally loads

But index goes to page 2 no problem!
https://caminhod.com.br/page/2/

What could that be? the codes are very similiar!
