Running VMware NSX-T 3.2.1 on a clean install, no previous upgrade. Home lab is not sitting around doing much other than whatever idle tasks might be going on with the appliance. I decided to log in and BAM! The system section was not loading

Under System>>Configuration the following error would appear

I was able to navigate to check the basic health of my managers, and checked ‘View Details’ for each one; everything was up, all green, and space utilization looked good.

From the VM console logged in as admin, I tried ‘restart services controller ‘and no success.
While troubleshooting and looking for KBs and forums on the web, when running ‘get managers’ from admin console, one of my managers was in Standby, but then there was some intermittent activity where all went into Standby for a brief moment.
Not just this happening but my Appliances GUI was also now switching between ‘Healthy’ & Degraded.

Next step was to reboot one appliance at a time, which did not seem to fix the issue.
After taking a break and happen to be doing something else in the home lab, I had to shut down and restart the vCenter, well I happen to check later on in the day and NSX was able to load with no problems.
I’m going to keep this up in the event the issue comes around, I plan on updating.
