Remote Admin on R9000 Fails

I have activated "Dynamic DNS" and it shows in status that it is working and updated correctly.  I have also activated "Remote Management" using the standard port 8443.  "Remote Management Address" shows:  https://my_dynamic_dns:8443 for remote admin access.  When I try and remote in from the internet, I am getting a "Your connection to this site is NOT secure"  When I view the reason, it show the server certificate does not match the web address.  The router is expecting "Routerlogin.net".    How do I fix this error?  I believe this may have happened with the recent firmware upgrade.  Current router firmware is V1.0.2.40.  Any help would be appreciated!
