I'm getting "stratum refused connection" errors every time. I have checked and double checked that I'm using username.workername and correct password.
All systems running normal here, people are mining and stratum is responding. What's your complete command line?
After going through the logs, I found:
[2017-07-14 06:18:17.630] [DEBUG] [default] - Pool chaincoin Thread 1 Unauthorized newmmz.chain1:XXXXX [111.220.93.213] (XXXXX put there to obfuscate).
Make sure to have the Worker name and password in your ccminer line like so:
-u newmmz.workername -p password
