Key in node Cesium+

I move my node Cesium+ to new VPS and resync. All is ok, except by keys. I set my credentials in file: elasticsearch.yml in values:

# Keys
duniter.keyring.salt: 'MY_SALT'
duniter.keyring.password: 'MY_PASS'

But, in Cesium client I can other public key: DnY8C42VkYbvgZy8jf1JrCdzPtx45ddorevB1w8nCgxW:4AG


How to set correctly my keys?

Thanks in advance.
