Hi!
Yes, this pool have an issue with X11 algorithm realization: it returns 512 bit hash instead of 256 bit.
Cutting half of it (as it is done in other realization) doesn't solve the problem.
Unfortunately, I had no motivation to dig into the root cause analysis, so we need someone who will.

Hi, the only work around I have (and it's not much of a work around) is to turn off vardiff and fix the difficulty for an X11 pool to 0.001 This allows the miner to get valid shares but unfortunaltey also makes it think it has found lots of valid blocks which the coin daemon then rejects. I am trying to get higher hashrate X11 miners working but at the moment the fixed low difficulty is stopping them from getting to their full potential. Thanks!
