Hi, I'm using codesys v3.5 sp21 software. I have downloaded the sample opc ua client project from https://content.helpme-codesys.com/en/CODESYS%20Examples/_ex_uacapi_example.html and i tested connecting to "prosys opc ua simulation server". Through Anonymous connection it is connecting to server and can read data. Later tried to connect using username and password. First got a SECURITY_CHECKS_FAILED error, trusted the client certificate in the server and this issue resolved. Next got an INVALID_CERTIFICATE...
Unable to Connect To OPC Ua server through UserName identity
