Go Central Administration >> Alternate Access Mapping and Choose your web application
And click on Edit Public URLs and then add HTTPS URL
And Click Save.
Now try to brows your site with HTTPS URL
Notes:
Issues:
Issue #1: Mixed HTTP and HTTPS Content
If you login with HTTPS URL and then redirect the user to HTTP , the browser will ask the user again to login with HTTP URL.
Fix:
Go To Central Administration
Open Alternate Access Mapping (AAM)
Select your will application from the dropdown menu on top right
Click on Edit Public URLs and remove HTTPS URL
Click on Add Internal URLs and add HTTPS URL and select the same zone as HTTP URL
