APEX

I am using Nginx as proxy server for my Oracle APEX App. When I run my custom domain mycustomdomain.com my APEX app home page opens but I have 3 problems:

1. First time opening in browser mycustomdomain.com I get mycustomdomain.com/ords/r/myapp/sample-charts/home. The second time I open it in the same browser it opens as mycustomdomain.com/home as I want it to be always and not just from the second time.

2. When I click in my navigation bar in the app to go to other page then homepage that was first to open they open as mycustomdomain.com/ords/r/myapp/sample-charts/somepagename and not mycustomdomain.com/somepagename. Also when opening any of them, I get error Failed to load resource: the server responded with a status of 403 (Forbidden). When I run by hand in browsermycustomdomain.com/somepagename it works but there is also the same error 403.

3. When I go back from any page to home page it does not take me to mycustomdomain.com/home it takes me to mycustomdomain.com/ords/r/myapp/sample-charts/home.

   Here is the code:

   #http server block(port 80) -Redirects to HTTPS

   #Redirect all HTTP traffic to HTTPS
