Paginator does not load on site.com/blog

I am building a blog with Jekyll.

Using Paginate plugin for posts. It loads fine on github.masteringmdm.com/blog in my local development environment on Windows, but it does not load fine on GitHub.

For this to load on GitHub I have to extra slash “/”, I have to use github.masteringmdm.com/blog/.

Any help would be much appreciated.

This has been sorted. Added below in _config.yml
