I mined on btc.com EU pool yesterday with 50xS9, at one point around 1:20 AM CET all miners stop sending shares. They where online but no shares submitted, switch to US pool everything ok. This happends from time to time what kind of issue is this? should i change some config on my side?
Anybody else having the same issue? I have a similar setup, and mine on btc.com US pool both from US and Europe. My S9 rigs based in the US are doing fine, but rigs based in EU have exactly the same issue, and always during night in Europe.
