MazaCoin Solo Mining

[Rewok123]

Hi,

First of all excuse me for my bad English
In my basement i've 7 Antminer S1 and i want to mine Mazacoin solo.
4 of them have a connection to my MazaCoin wallet. But the other 3 won't connect with the server.

If i try this command in the terminal "sudo ./mazacoind getinfo" i never get a response.
It looks like a timeout problem....

Does anyone else has this problems?

Thank you
