Solo mining, noob

Just want to try it
I've started geth with claymore connected to it but the miner says only this:

ETH: Stratum - Connected (127.0.0.1:8545)
ETH: Job timeout, disconnect, retry in 20 sec...
ETH: Stratum - connecting to '127.0.0.1' <127.0.0.1> port 8545
ETH: Stratum - Connected (127.0.0.1:8545)
ETH: Job timeout, disconnect, retry in 20 sec...
ETH: Stratum - connecting to '127.0.0.1' <127.0.0.1> port 8545
ETH: Stratum - Connected (127.0.0.1:8545)
ETH: Job timeout, disconnect, retry in 20 sec...

how to get some jobs for the miner?
