Hello.

This looks like that the server is not compliant with the OPC UA spec, likely. Which server is that?
The actual signature algorithm URI is empty, but it should be the value indicated in the message.

Regards

Hi,
I'm using the OPClabs(5.71.231.1) libraries version.

connecting to an OPC-UA server with security none when I try to browse the variables there is this exception below:
Also in the EasyOpcUADemo.exe demo application I get the same exception.

This below is what is reported as an exception:
UA SDK error (Opc.UA.ServiceResult=0x80130000) in 'static Session.Create'. OPC UA service result - {BadSecurityChecksFailed}. Unexpected signature algorithm for Basic256/Basic128Rsa15:+ Connection attempt #1; last connected at 01/01/0001 00:00:00 (local); unconnected for 00:00:00.+ The endpoint URL string used was "opc.tcp://192.168.3.44:4870".+ The client method called (or event/callback invoked) was 'ReadMultiple[1]'

Can you help me please?

Thanks
