Hello,
Our application uses Prosys OPC UA server SDK v7.5.1.
There is a connection attempt every 10 minutes on port 4840, which ends in an exception. The application log is full of them.
Is there a way to disable this feature?
Thanks in advance.
Best Regards
Denis

You can disable the registration to the Local Discovery Server (LDS) by calling
as also shown in the ‘SampleConsoleServer’, if you run it with the ‘-d-‘ option .
The LDS is an optional component that can be installed, and the servers are typically trying to register to it by default, but you can also opt out of that – or make it optional within your own application.

And, since it seems I answered the question in relation to the SDK for Java, although you asked in relation to Delphi and Sentrol, the proper answer is to set:
