My IP SSL unable to shows the contents of my domain

I am trying to set up reverse proxy for https for my wordpress domain. So far, the ip with ssl is already set up but there is a problem when i am accessing the link of my article.

For example, the website is : https://example.com and i just create a post with link https://example.com/test_post/ with my ip is : https://111.111.111.111 but when i try to access https://111.111.111.111/test_post/ , it return with 404 Not Found. Can i request for a help to how i can set it so that the ip also can shows everything inside my domain? This is how my line looks like

Thank you very much
