setting up test environment in Hyper-V 2012R2, openSUSE Leap 15.1, using EMQ X Broker version 3.1 2-node cluster, HAProxy v1.6.
Everything works except for when I tried to run a mosquitto_sub.exe command to the HA_Proxy IP address. I get an Error: "A network protocol error occurred when communicating with the broker." I can run a mosquitto_sub.exe command to the IP of either broker and it works fine - can send/receive messages. Attached is haproxy.cfg file.
