I found that in same building 2 different internet providers, 1 working perfect and other have connection problem, so its nicehash isp or dns problem, not the miners problem...
You can open same .bat file with any other miner like ccminer and it would be same problem,
Last 4 hours the eu stratum not working with all internet providers, test it like I wrote and you will get same result....
Other than eu stratums works for both location but it seems that devs fee goes to eu stratum....
For now for 1 my location i have started to mine with coolminer on nicehash, its working perfect...
