OPC UA connection problem

Yes, strange...But you know what? The real strange thing is that None of that devices allow me to connect, but I have a saved configuration with wich I can connect to the PLC and this is what terminal says when i use it:

May be you should start "from the scratch" and create a very simple "basic" server in simulation mode, get successfully connected to OPC UA toolkit, and then step by step add some more things and check when it stopped running.

I created a very basic instruction, how it works for me — How to setup simple OPC UA Server in B&R AS.

May be this will help, at least check the differences.

I don't have access to B&R PLC.
It's provided by a third party company as it is with all my application, I need to create only a client.
And as all my devices, I can connect to them via OPC-UA correctly via PYTHON.

If I try to connect to a SIEMENS device ( I can connect via python correctly with it) I get a certificate error instead 😞

Are you able to connect via Python without certification and from UA Expert as well? Interesting. Looks like old OPC connection's Hell slowly coming back to us.

Exactely, Python and UA Expert conenct to devices without any problem. Labview gives errors 😞
I'm evaluating to buy a license for the toolkit but at the moment it doesn't seems the be the best way...
