Unknown Algorithm and login error code 6

[gery89]

Hello everybody.

I making a local pool. All runs right without error. The problem are with xmrig appear this error. If I put algo cn/0 in xmrig, the miner connects and work's but only makes 1000hs when normally makes 4500hs with other pools for this reason i'm trying to made auto by pool.
If I put some rx algo, says the same error, unknown algorithm.

How can make the pool set algorithm, and how can make to use the same algo as minerxmr?

I attached a photo. My confi.json are the same as the installation guide, only changed the host for website. .Redis works right

Thanks
