I'm trying to add a new OPC UA client :
endpoint url : opc.tcp://10.247.10.2:4840
allow unsecured connections is on
authentification is Anonymous
inside the client certificate I created a new certificate
In the server certificate I saw an untrusted certificate and added it into the trusted ones
Now when I add this OPC UA client, the values says : 514 - Server Certificate subject mismatch
What does this mean and how can I solve this?
