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...

It is a miner program problem it runs fine till it tries and switches to collect the DEV fee even the DEV said he has the same problem with it on Nicehash!!! Nicehash sucks anyway to much in fees and way to high for payouts take me a month to mine on nicehash to get paid and thats with 18 gpus
I also believe you didn't run the program long enough to get to where it switches to the dev fee try running it for 1 hr
