Lol, I tried on solo-mode but I don't get any coins... I found some blocks hours ago but nothing coins..
At someone the solo-mode work fine ?
Solo mining does work but the pool has a high hashrate so you may not be getting many blocks

Coins mature after 2000 blocks. Try the listtransactions rpc command to see your immature coins.
I solo mined as testing before CRT went public, tried both testnet and mainnet and they worked just fined. I restarted the blockchain after testing was completed.
