I get this exception when I try to connect a remote client to my server. My Server is running RMI Server fine, and there no firewall installed. How to fix that issue ?

Try to start the RMI registry using 

start rmiregistry

for default port or 

rmiregistry <port_no>

for a specified port.

Check all you network adapters ,some time a VM network adapter interferes in this way . Which is you current localhost or 127.0.0.1 is not any more referring to you host name or current machine ,which then create a connection refused problem. My General Recommendation is:

1.To check or disable unwanted VM or Network Adapters

2.Ping 127.0.0.1

3.Disable Firewall and Test if all the above doesn't work 

4.Add security Manager with a policy file on you server if you haven't done that.

Is IPSERVER mapped in /etc/hosts file to the IP address you want? Check what you get when you do a hostname -i or hostname.

Try putting your IP address instead of the domain name.

You have not mentioned which OS you are using, if everything is correct in terms of code and firewall then you may need to check the host entries or ip table rules.
