Hi engineer!
After updating the Firmware from version 2021.0.6 to version 2021.9, I got an error about OPC UA Client DA/UA at Factory IO as shown below. The error is detailed as „Endponit does not support the users identity type provided“. Before updating the Firmware, the above error did not appear. Thanks engineer!
The OPC UA Server provides a number of security policies (e.g. „AES 256“), which you can see in the OPC UA configuration window in PLCnext Engineer.
Some of the less secure policies have been disabled in more recent versions of firmware. Perhaps your OPC UA client was using one of these less-secure security policies (e.g. 128 RSA15).
There may be a clue in the "users identity type provided" to the server by the OPC UA client. What identity type is provided to the OPC UA server?
Are there any log files available from the OPC UA client that might give more information about what the problem is?
Also, are you able to connect to the OPC UA server using UA Expert (from Unified Automation), using the same Security Policy and credentials that are being used by the Factory IO client?
Hello, this is a known issue. You must disable some algorithms in the OPC UA server settings in PLCnext Engineer. After disabling „AES 128 SHA256 OAEP“ and „AES 256 SHA256 RSA PSS“ the connection works.
To clarify:
The known issue that Stefan describes is an issue with Factory IO, not with the OPC UA server.
Hi engineer! I fixed it by change the information of Gateway on Web-based.
