Go to the communication settings of your device, then find your device.
In the same tab, you can see at the top, the menu Device, Change Runtime Security Policy.
You also need to create a certificate for the OPC UA Server running on the Device and when UaExpert has tried to connect, you need to accept the certificate. For this you can go to the menu View-Security Screen. Then go to devices, create your own certificate and move the quarantined certificate of UaExpert to the Trusted Certificates.

Thanks for your answer. I completed what you say. I wonder whether is it possible to make an entry with password. I downloaded Uaexpert to different machines in the same network. I connected the main machine directly. I want to block this situation. Need a encrypted connection, is it possible?
