I am getting problems connecting to Ignition OPC-UA Server.

The OPC-UA module is running and the certificates have been Regenerated and the module restarted. It used to work before but since I installed the license and changed the network of my computer it does not work. I post the error here, I hope you can help me.

Check the username and password you’ve configured the connection with - the server is telling you that you’ve got it wrong.
