If it was running fine until now it could be a hardware problem...
Sounds stupid, but have you tried to turn it off and on again

Are you remotely connected to your miner?
If not, check your network-connection.

One of my rigs showed that "fault detected on GPU X" error once and after i switched cables to another router, everything's working fine again.
