Hi
First of all, you need to check the hosts file on your client system.
hosts file has to include some information such as "host/ipaddress" and so forth..
In my case, I found out that the issue is related to OS System.
If I installed IQ16 SP08 on window 2008 R2 (English version) or added a package of english language.
And then I changed display language from korean to english.
I succeeded to log in to cockpit console.
And the cockpit related log files are helpful to investigate the root causes.
thanks
