Anyone use the app on their phone? I have "CKPool" on my iPhone 6 and I use it to periodically check my workers throughout the day whenever I'm "on the go". Today I noticed under "configuration" - "information" - "problems detected:" - "no internet access", both when using wifi and while on my AT&T LTE. I love the app, I get notifications instantly on blocks found and payouts. Just noticed it quit working for me today. 
I just checked the copy I have on my iPhone and sure enough it is down. vh will probably need to reboot it on his side. Check out his thread at

will do. thank you very much for checking and confirming it's not just on my end.
