OPC UA Client failed to connect to Server

[HichemB]

Hello,

I am performing a very simple OPC UA Sever-Client Communication (Same as the one in the Examples).

The communication should be secure (using the generated certification).

Actually I generated Two Certificates (For the client and the server) and added them to configuration.

My Problem is that I cannot the client to the server. I am having this error. (Although the file exists)

Can anyone please help me which certificates to use for the configuration because the "Create Certificate.vi" generate two files (*.der & *.pem).

Thank you in advance.

Solved!

I just used the public keys (*.der) and ignored the other generated private keys.
