Unlocker No block candidates in redis

After checking the log it seems to have been repeating this for almost a week. Is this normal? I have not unlocked a block before and this is my first time running my own pool.

Try to use the cryptominer with your IP and Port for the Pool. Please add before you start mining your own created wallet address in wallet.txt in the cryptominer folder.

In Cryptominer you can see, miner is connected to pool or not. Then its a port problem in your pool.
