Hello oded, Quick first thought... does your Postgresql config define a bind address of the old IP? That would prevent it from listening on the new address. But in order to properly diagnose a problem, you will need to provide some more details from the output produced by Postgres. What does the log file say? Does process monitor even show the processes running? Thanks. -With kind regards, Peter ----- Original Message ----- From: "oded" <odedi17@xxxxxxxxx> To: pgsql-admin@xxxxxxxxxxxxxx Sent: Monday, May 23, 2016 4:45:57 AM Subject: Connection refused error message after ip change hello i have windows server with pgsql-9.2 for ca wily interscope. i change the ip address in the server, and from that point the psotgressql is not working. i uninstall the sql+wily and install in again, and it only install the wily and not the sql. i get error message: Connection refused.
