The Matlab OPC UA Client does not connect to the OPC UA Server (OPC CoDeSys V3)

Why the client doesn't connect to the server.? I thought I did everything according to the instructions in the help. Who has an idea?

Same problem here:

I'm running a raspberry Pi with Codesys Image and the OPC UA Server on the Pi is correctly configured and can be reached and browsed with UA Expert.

But the OPC UA Client from MATLAB fails to connect to server!

Any help would be appreciated...

Hi Aschmann, Jonas,

Which MATLAB version are you using? This issue could be happening due to the server taking more time to respond to the connection request. I'd suggest logging the OPC UA packets using an application like Wireshark to see if/what the OPC UA server returns in response to the connection request. This could help root cause the issue.

Hi,

Try to make your connection "Trust" in OPC UA aerver. Then it will work.
