Hi,
I’m trying to connect to an OPC UA Client written with Prosys using the Prosys Sample Client. I get the certificate message and can accept it (it says the certificate is invalid in some form, but I can still just accept it).
But after that it takes about 2 seconds and I get the message: Failed to CreateSession.. StatusCode=Bad_UnexpectedError (0x80010000 – An unexpected error occured).
Do you know common causes for this? And what I might need to do?
Thanks & Greetings

The usual reason for Bad_Unexpected error is an unexpected exception in the server implementation.
You write that you are “trying to connect to an OPC UA Client”, but did you mean you are connecting to your own server written with Sentrol, too? Can you connect to the UaSampleServer, though?
If the server certificate is invalid, it may help to regenerate it. If you remove (rename) the old one in PKI\CA\private folder, the application should create a new one automatically.
