I have a 1 master and 2 nodes configured with Istio and metallb, but I cant get to works a postgresql stetefullset. I also have configured a DNS record to redirect the request.

All pods and statefulset are Runing, but I get this error when I try to connect:

"Expected authentication request from server, but received H"

What im doing wrong?
