I am checking Redis high availability solution via configuration of master and slave Redis Kubernetes pods and sentinel on top of it. For failover of external client connections, I installed haproxy pod. I encountered with some issue while started testing the configuration:

1. Redis is closing forwarding connections from HAPROXY - client reporting error

Error: Server closed the connection.

BTW: if Redis is configured with an empty password, the connection is passing OK.

I appreciate any idea and advice. My HA proxy cfg file has the following entries:

global
    daemon
    maxconn 500

defaults
    mode http
    timeout connect 5000ms
    timeout client 50000ms
    timeout         server 50000ms

frontend rotatingproxies
    bind *:3000
    default_backend rotateproxy
    option http_proxy
    option http-use-proxy-header

backend rotateproxy
    option http_proxy 
    server proxyserver user:pass@domain.com:9999
    server proxyserver user:pass@domain.com:9999
    balance roundrobin
