When i connect to haproxy balancer and try execute every queries psql tell me:  
server closed the connection unexpectedly  
This probably means the server terminated abnormally  
before or while processing the request.  
The connection to the server was lost. Attempting reset: Succeeded.  
I repeat this command and now it works, but why?  
When i use them direct on current base it works without errors, and reserve server got it

My configuration:  
Main server: 192.168.8.201  
keepalived for 192.168.8.210  
haproxy  
patroni  
etcd  
postgresql look for \*:5432

Fail-over server: 192.168.8.202  
keepalived for 192.168.8.210  
haproxy  
patroni  
etcd(deep copy of previous, because onlye 2 machines, without changes on future)  
postgresql look \*:5432

Haproxy config:
