This is back - interestingly http://pool.burstmining.club/ worked without this issue for days.
Testing, Tross Pool would not run with jMiner at all - Extended list of:
"Unable to get mining info from wallet" - ignoring the start of new blocks.
Blago Miner worked and has 100% quality.
Switching back to pool.burstmining.club - jMiner now does not work still...
Blago Miner works and has 100% quality...
Updated to latest jMiner version, no change.
