Software update Manager - could not connect to host <host> and port 4241

[Former Member]

hi all,

When I started GUI with DSUGui.bat I got an error

Could not connect to host <host> and port 4241.

java.net.ConnectException: Connection refused: connect

java.net.ConnectException: Connection refused: connect

I have Firewall already disconected.

What could be wrong?

Hi Mirko,

Connection refused means that the connection was able to reach the host but not able to reach this port.

Check if the application is indeed running and listening at 4241. In most cases of this issue, some error happened at the application and this application is not running anymore.

Thank you Mauricio for help ...

How can I check if SUM application is still running and listening at 4241?

Hi Mirko,

I would recommend you going to the OS level on the host where this application runs and check if the process is still alive and do a netstat -an and see if the port is still allocated.

This port is not allocated ...

Hi Mirko,

Then the application is not running, simply start it.

Hi Mauricio,

I'm facing the same issue, how do you start the application? I don't mean with SUM. Did you start a special service? If yes, what is the name of the service?

Thanks

Hello Mauricio, Koku,

Can you guys tell me how exactly you resolved this issue. I have not been able to resolve this issue yet. I have restarted the server, the application (SUM) is running, changed thr port in config file, used SUM 1.0 SP10 and 1.0 SP09 patch 9 but none of them resolved the issue. Can you please help me out here as it is getting really frustrating..

Thank you

Hello,

Our issue is resolved. It is a Linux system and after a system restart the firewall was enabled again. Disabling the firewall resolved the issue.
