what’s the server in this case?

i think i deleted it by mistake

that was a concern I had, that disconnected by server says that it was not a graceful disconnect - possibly too many connections are being opened, or a connection being opened and not responded to, so the server disconnects the remote end forcefully (e.g. with a RST instead of a FIN)

yes , we are trying to make a lot of connections . but is there a work around for it ? any method to maintain a large number of connections ?

that would be at your database

its outside the cluster . we have postgre running on rds but inside the same virtual network
