Weird interaction with nicehash at start sometimes

[mrbrdo]

Sometimes something weird happens with nicehash when starting sgminer, it interprets what is going on as if all pools are offline. After starting sgminer again it starts without problems. I think this only happens when using nicehash's settings via password e.g. I am using: "f0=0;f2=0;f3=3.85;f4=2.69;f5=331.5;f6=2.58;f7=6.5;c0=0;c2=0;c3=0.1;c4=0.1;c5=0.16;c6=0.1;c7=0.1"

It might be a nicehash issue but probably sgminer could handle this better.

I wonder is it possible that this is some form of DDOS protection that throttles connections on nicehash's end?

I think I'm whitelisted on nicehash for testing so not sure if they throttle me. It's possible but I wonder what setup_stratum_socket fail means, didn't look into it yet. Since the other pools failed with timeout.
