ERROR: CheckProofOfWork(): hash doesn't match nBits
We are aware of the current "stuck blockchain" affecting Solaris. The cause has been identified and our developers are working on a fix ASAP. Sorry for any inconveniences caused.
Excuse me for the n00b question, is there any point to keep my miners mining XLR while the chain is stuck? Or the work "lost"?
It is better to switch your miners to another coin, the developers will soon fix the problem and you will be able to return to mining XLR.
