Error Message
Dashboard doesn't display anything (Gray page)

Cause
This kind of situations can be happened by name resolution mismatching .

Ex.)
- Control Panel\All Control Panel Items\System
Computer name: dpcm
Full computer name: dpcm

- nslookup dpcm
Name: dpcm.dplab.net
Addresses: 192.168.100.100

In this case, "Full computer name" is not FQDN(Fully Qualified Domain Name) .
The "Full computer name" is short name , but FQDN returns from DNS .

Dashboard page will be formed as https://dpcm:7116 .
Even though "dpcm" is specified at GUI to connect, it will be converted to "dpcm.dplab.net" automatically by the name resolution setting .
GUI will try to refer to https://dpcm.dplab.net:7116 that is not valid .

Workaround / Fix
This situation can be avoided by adding an entry with short name in hosts file at GUI client system .
Specified short name won't be converted anymore and https://dpcm:7116 can be accessed .

Ex.)
192.168.100.100 dpcm dpcm.dplab.net
