I tried to mine SIBcoin. However, I see the "Stratum authentication failed" in the screen.

I used all defaults and the pool by default is sib.suprnova.cc:3458, intensity is set to 21.
I didn't modify worker name or anything else.
Suprnova seems to support anonymous mining on some coins (a few equihash ones) However, I'm not sure about SIB coin.  I might need to create an account.

Anyone wanna comment?
