Unable to access the rhem-reports after changing the port from 8443 to 443 in RHEV 3.1

Issue

• I have migrated from rhevm3.0 to rhevm3.1 and used knowledge solution 291993 to change the port from 8443 to 443 for https. Now when I click on the reports portal, why is it redirecting me to https://rhevm.example.com:8443/rhevm-reports again and again?
• The RHEV Landing page links to the Reports Portal on 8443, but the Reports Portal is on 443.
