P4 connection refused

Hi guys,

Ive a problem when configuring Solution Manager Diagnostics in order to get EWA for my NW2004s pure Java Development system.

The issue is, after installing succesfully SMD and Introscope Agent, when running Setup Wizard for managed systems in Diagnostics.

Logs says:

An error occured while communicating with Message Server 10.193.4.54:50000 through the host ovdev : Error to retrieve the process from Message Server (detail: java.io.IOException: AttachToMessageServe

r(): No answer from message server within 60 sec.); nested exception is:

java.io.IOException: AttachToMessageServer(): No answer from message server within 60 sec.(cause=java.io.IOException AttachToMessageServer(): No answer from message server within 60 sec.)

Please check Message Server host/port, or enter the P4 ports in cluster table.

Detailed log i found says:

I have tested P4 connection via Visual admin, as suggested in other post and it works fine. Last night we have restarted both servers (VD1,development server, and VS1, solution manager server). I still dont know if i can get more detailed info.

Any ideas?

Regards!!
