There were interoperability issues against the C/.NET servers before Java SDK version 2.1.2, since the specification was different to those implementations. Which version of the SDK are you using?
The change was mentioned in the release notes as well: https://downloads.prosysopc.com/opcua/release_notes2.1.2-478.html

Sorry for the late response.
A possible reason is that the specification is actually defining a wrong URL for the AsymmetricSignatureAlgorithm, ‘http://www.w3.org/2000/09/xmldsig#rsa-sha256’, whereas all the implementations actually use the correct one, ‘http://www.w3.org/2001/04/xmldsig-more#rsa-sha256’. This was fixed also for the Java stack in version 2.1.2, but the respective change was not taken to the specification version 1.03 either. Hopefully, there will be an errata that fixes it finally. The following Mantis issue can be used to track it:

I discussed this with Unified Automation and heard that there were interoperability issues with the OPC Foundation stack implementations in last week’s Interoperability Workshop – and these issues were fixed in the OPC Foundation stacks.
Our Java and Unified Automation implementations should be interoperable.
But which stack implementation are you using? OPC Foundation’s .NET or C and which version?
