Have you tried port 4712 while connecting HTTPS?
You also may want to check here: /etc/mwg-ui/internal_connector
There are some references to the ports.
Yea, we tried it on port 4712. We corrected the issue by adding the secondary 5500 and adding it to the centralized management. This allowed us to change the settings back. I'm working with support current to determine why https via port 4712 is not accessible at all though.
I appreciate the input.
