504 Gateway Time-out

[janfiedler]

Hi, 504 Gateway Time-out more often happening when start sam API call. It is take 1 hour before carriota field nginx return 504 error. I think 1 hour is to much time. Even if someone use field for PoW, 1 hour is to much. Can you think about it to lower limit?

Thank you and good job done with field btw ;)
