Good morning,
I frequently encounter the following error when connecting via OPC-UA:

 

Date Time Level Source Event
19/06/2025 13:01:03 Warning OPC UA Client B&R | Read request failed on device. | Status description = 'The operation timed out.', Status code = 0X800A0000.

 

Thank you.

Hello,

 

As a next step, We would recommend capturing unencrypted packets using the Wireshark tool to help observe the communication at the wire level.

 

Alternatively, you may consider submitting a support ticket with the Kepware Technical Support team, who would be happy to assist you in analyzing the packet data. Thanks

Good morning,

I’ve already tried this solution in the past, but it didn’t solve the issue.
I had set the value to 3000 ms.
