Hi, is it right that we have found this block?

No.. Sadly..
https://btc.com/stats/pool/unknown622066 is attributed to an unknown pool.. Not sure why they would try and associate it with CKPool..
There are a few private pools using the ckpool software. Since the default software includes the /ckpool/ signature in a block, they mistakenly attribute it to this pool, but this pool has a ckpool.org signature as well.
