vSphere Server Appliance 6.5: Could not connect to one or more vCenter Server systems: https://:443/sdk

Do you get the next error in vSphere Web Client 6.x?:

Could not connect to one or more vCenter Server systems:
https://<IP-adres or FQDN>:443/sdk

If you open the URL, you get this error:

503 Service Unavailable (Failed to connect to endpoint: [N7Vmacore4Http16LocalServiceSpecE:0x00007f24400047c0] _serverNamespace = /sdk action = Allow _port = 8085)

Are you using the appliance? My problem was solved by the next solutions:

I seem to have fixed my issue by simply typing in a System name in the dialogue pictured below, instead of leaving it blank, which relied on the DHCP reservation/DNS entry in my router that worked under 6.0U2.

I've now survived 5 ESXi reboots, using ESXi host reboot, which was set to shut down all VMs gracefully, and to restart VCSA automatically.

I will continue to test and reboot, but first, a flight to catch, with my server onboard, of course ;-)

Here's how I was doing 6.0U2 or 6.5 installs, choosing DHCP, and leaving System name blank (but setting up a DHCP reservation for the VM's MAC address, and setting up a DNS name, by suspending the VCSA 6.5 appliance moments after the power up button appears, and grabbing the fresh  VM's MAC, then resuming)

  

I don't use DDNS:

  but figured I'd try to put in a System name anyway:

 Five reboots later, I seem to be good, used to fail on first or second reboot/restart of VCSA.

VMware vSphere Essentials V6 - Migrating storage tip.

The migration option "Change storage only" is not allowed in VMware vSphere Essentials.

If you want to migrate a VM storage from one datastore to another, then use "Change both compute resource and storage".

After the migration is completed, use "Change compute resource only"option to migrate the VM back to his original host.

This way you can live migrate the storage of you VM. It takes more time and work, but the VM stays online.
