Block Reward problem?

We’ve successfully mined.
There are many wallets with a balance of zero.

When will the Block Reward be paid?

채굴에 성공하였는데도.
Balance가 0인 지갑들이 많습니다.

Block Reward는 언제 지급됩니까?

You will receive your mining reward when we run housekeeping. The network is currently holding it due to a performance issue that we are working on.

thank you for the reply

I have question,
What do you mean housekeeping?

Currently, the coins I mined are not confirmed in the CTC Client or block list on web site.
The result of searching with my public key through REST API and the information of the block checked on the website are different. Is this because of housekeeping?
