Upon Upgrade to 9.3.9316, I can't get to the GMS GUI.
If you have recently upgraded to GMS 9.3 build 9316 you may have found that you can get no longer get to the login page for GMS. Please follow these steps to restore access.
Just add :8443 to your address and you will be able to access GMS again.
You can then Go to Console and then to Appliance
In appliance, go to Deployment and then Settings and set the http and https ports back to the previous defaults of 80 and 443.
After this you will want to restart the server and your access will be back to the standard ports.
