Hi everyone,  
I’m encountering an issue with the OPC UA connection in IIoT Connector. I hope someone can help troubleshoot. After enabling OPC UA, the health status light remains yellow in the “Health status” tab.

The manual mentions checking detailed parameters, but I don’t see conflicts.

Could this be related to certificate issues or other hidden settings?

Any insights would be appreciated! Thanks.

Best regards,  
Shiyun
