TV general is enabled

have looked at log

The error says Mac address mismatch but i have checked on papiao and
in stalker and they are the same.
i did change the initial mac address from 00:1A:79 to 00:1A:78



Any ideas?

Found the problem
changed the MAC from 00:1A:78 to 00:1A:79
at the server and on the stalker and it worked thanks
