Thank you for input. After two days of trying various things they are up and running again. Unfortunately i am unable to pinpoint which action brought them back online. But it was not a cyber attack as i had feared. My computers were fine but the ASICs were not working, and i'm guessing it was related to the network.
Dont you try use vpn if it works just reply here or pm me i will give you a link with cracked vpn.... I think your ip is wrong or it blocks from the server..
you may try also report it in the server....
