Except home page other pages are showing "Not Found Error"

My website has 5 pages: The home page works fine but with the rest of all 4 pages I am getting the error “Not Found- The requested URL was not found on this server.”

Home Page: https://rixology.in/contact/
About: https://rixology.in/contact/
Services: https://rixology.in/contact/
Projects: https://rixology.in/contact/

Can anyone help me with it.?

The theme astra you’re using does not seem to be correctly configured with the wordpress Menu. Configuring that would fix the issue. 404 is served from your host.
