Hi,

I ran the SampleConsoleServer out of the box to test for connection with Softing OPC Toolbox.
In the log of the server, I received this warning.

03/11/2015 13:45:50.156 WARN Could not register server (online) to Discovery Server at opc.tcp://localhost:4840 Cause: Failed to retrieve endpoints. The server is not available: opc.tcp://localhost:4840

Could you assist me on this?

Thanks.

The server will try to register itself automatically to the Local Discovery Server, which is a separate component, available from OPC Foundation: https://opcfoundation.org/developer-tools/developer-kits-unified-architecture/local-discovery-server-lds/

If you know that the LDS is not available, you can comment out the line where ‘server.setDiscoveryServerAddress(discoveryAddress)’ is called or provide cmd line option -d- for the SampleConsoleServer.

I installed the local discovery server on my system and now received another warning.

03/12/2015 09:42:50.160 WARN Could not register server (online) to Discovery Server at opc.tcp://localhost:4840 Cause: Failed to create secure channel to server: : opc.tcp://INSTSGP0002N.bosch-si.com:4840 [http://opcfoundation.org/UA/SecurityPolicy#Basic128Rsa15,SignAndEncrypt]

How do I create this secure channel to the server?

OK, yes this is expected as well. The registration requires a secure connection. This on the other hands requires that the Local Discovery Server accepts the certificate of your server. You will need to go the certificate store of LDS (‘C:\ProgramData\OPC Foundation\UA\Discovery\pki\’) and move the server certificate from ‘rejected’ to the ‘trusted\certs’. The server will trust the LDS certificate automatically.

Hi,

Hi,

This is weird. Can you connect to the server with any client?
Because the only way for that error to happen if there are no endpoints in the server which should be impossible.

Can you add the following line to the log.properties file located in the same directory as SampleConsoleServer:
log4j.logger.com.prosysopc.ua.server.UaServer=DEBUG
and rerun/paste log here.

I added (log4j.logger.com.prosysopc.ua.server.UaServer=DEBUG) in the log.properties file,

Looks like this issue wasn’t ever checked properly. turns out that the server does not specify the DiscoveryUrls properly, and the current LDS gives and error for it, whereas an older version did not.

But, in fact, this only happens during the first offline registration – the following online registration works fine.

However, this will be fixed in Java SDK 2.2.6
