New to mining Burst

[Bliz_Blaz]

Any help appreciated. I keep getting the same error after every block "Error: Failed to 'getBlock' to find last winner. last winner 'N/A', walletServer out of sync" I looked in FAQ and found nothing about this. I am using jminer on a pool (https://0-100-pool.burst.cryptoguru.org/?) to an online wallet (https://wallet1.burstnation.com:8125/index.html) )
