Did you turn on TCP/IP processing on in SS Express. Normally, this protocol is off upon the initial SS Express installation. Both PowerBuilder IDE and the PowerServer needs to have this protocol active in SSX when you create a DB Profile in PB or a DataSource Connection profile is PS.

Already turn on everything. And also temporary turn off firewall.
Inform you again, I can connect from PowerBuilder IDE. But not PowerServer .
