Hi,

I found the thread from 2015 1st q where the same error is described:
http://forum.prosysopc.com/for…..tesession/
Below is what we get in log when our client (prosys SDK 2.2.0-552) is trying to connect to SINUMERIK OPCUA server.
With UaExpert connection is possible. The strange is that we don’t have problem with B&R which is described in mentioned thread.
Till now we didn’t experienced this problem with other servers only with SINUMERIK.
What was the final conclusion about this problem? Iinteroperability problems?
Do you have suggestion how to overwhelm this?

Best regards!

Hello,

Try setting

UaClient.setValidateDiscoveredEndpoints(false);

and let us know if this solves the issue.

By default, the endpoints are validated, but some servers provide different endpointUrls for the GetEndpoints and CreateSession service responses and may therefore fail at connection. The check is required for OPC UA compliance.

Hello,

Hi, I tried to set the value as suggested for DiscoveredEndpoints to false. However, I still get the same error.
INFO [Thread-1]: OPCClientUA thread start failed: Failed to create session channel to server : opc.tcp://xxx.xxx.xx.xxx:9999 [http://opcfoundation.org/UA/SecurityPolicy#None,None] .
However if I connect to this opc server using UAExpert client then I get no errors. The problem occurs only with Prosys Client or with Prosys Java SDK

Hi,

I’m sorry to hear that you are experiencing problems.

Can you post a larger snippet of the log that shows the createSessionChannel method call that ends up in “Failed to create session channel to server” error message? If possible, please use log level debug.

There shouldn’t be that much logging associated with this method call but if you end up with a huge log file which is impractical to post here on forum, you can also send an email to uajava-support prosysopc.com mailing list.
