Well, I tried setting up mercury I don't think I set up anything wrong I opened my ports on my firewall on my VPS, but still doing the same problem. Can anyone help?
You opened your ports In the inbound rule or outbound rule? And do you receive connection when trying to enter client? If you don't, then I think you opened your ports in the outbound rule therefore I would ask you to open the ports in inbound rule. If you receive connection and it drops, go to database server_setting and turn enable secure session from 1 to 0.
