Good day everyone!

I have a problem regarding iTALC 2.0. The installation on both MASTER and CLIENT works fine. I have installed all the dependencies needed. iTALC Master is running and same as with the iTALC Client. At first my problem is that I can't get into the MASTER GUI and it is because of the key pairing. What I did is that I copy the /etc/italc/keys/public/teacher from Master to Client and then it works I can now enter the MASTER GUI. The problem now is that when I try to connect to Client there is an error
"DESTINATION HOST UNREACHABLE" - in the Master GUI
"MS Logon II Authentication Failed" - in the Clients TERMINAL

CLIENT Screenshot - TERMINAL

MASTER Screenshot - GUI which I try to view the Master itself and it works fine but the Client had an error.

I hope someone could help me with this problem. Thanks in advance!
