Could not able to register the server to OPC UA LDS

[shrinivas.mt]

I tried to register the server to OPC UA LDS below is the code used for registration in APP Configuration.

Code: Select all

 <DiscoveryRegistration>
              <Enabled>true</Enabled>
              <RegistrationInterval>2</RegistrationInterval>
            </DiscoveryRegistration>

I'm getting the following error in server log file

|[Bad] Could not register with LDS. Re-registering in 4s. Url=opc.tcp://localhost:4840/|SocketException|No connection could be made because the target machine actively refused it [::1]:4840

i'm getting following error in UAExpert:

Discovery FindServersOnNetwork on opc.tcp://localhost:4840/UADiscovery failed (BadNotFound), falling back to FindServers

Discarding Server UA Local Discovery Server with URL opc.tcp://UT-LTP-111.ABC.in

I am using UA .NET SDK v3.02 (licensed) & OPC UA LDS v1.03 validated in UaExpert v1.5.1 for the testing.

Thanks for the help .
