[Rspamd-Users] Error with Rspamd Proxy and keepalived

[Emanuel Gonzalez]

Hello.!! step to explain in detail my infrastructure.

I use the rspamd proxy service on two servers, both communicated through keepalived service, using a floating ip for high service availability.

Randomly rspamd does not detect this floating IP and it shuts off abruptly

I see this error:

worker proxy config

milter = no;
bind_socket = 172.17.2.230:11332; ==> This is the floating IP

upstream {
            local {
                hosts = "localhost";
                default = true;
            }
            scan {
                hosts = "round-robin:172.17.2.106:11333:1,172.17.2.110:11333:1,172.17.2.114:11333:1,172.17.2.113:11333:1";
                default = true;
            }
        }

any ideas.?
