Assistance Needed: OPC UA Connection Issues

Hello,

I am experiencing issues while trying to connect to an OPC UA server using KEPServer. Below are the errors I encountered in the logs:

 

 
Date Time Level Source Event 11.12.2024 14:56:46 Warning OPC UA Client OPC UA CLIENT | Socket error occurred connecting. | Error = 10060, Details = 'A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond.'. 11.12.2024 14:56:46 Error OPC UA Client OPC UA CLIENT | Channel failed to connect. | Status description = 'Could not establish a network connection to remote server.', Status code = 0X80AC0000.
 

Additional Information:

  • Server Address: opc.tcp://10.20.20.113:4840
  • Username: orecifua1
  • Password: (Provided during setup)
  • Network: I have multiple network adapters and I am trying to ensure the connection uses the correct adapter.

Despite ensuring the server is reachable via ping, the OPC UA client fails to establish a connection. I have also checked for any firewall or network configuration issues, and everything seems to be in order.

Could anyone provide guidance on how to resolve this issue? Any help would be greatly appreciated.

Hello,

 

An application protocol such as OPC UA provides a particular service and relies on TCP to ensure reliable delivery of its service. Hence I would recommend you to check TCP Socket connectivity first from client PC using this article(https://www.ptc.com/en/support/article/CS293702) as a Prerequisites for validating the network connection​​​​​​​.

 

After that please verify configuration on both server and client side using this article(https://www.ptc.com/en/support/article/CS298913) ​​​​​​​. I would recommend you to try first with security as "None" before using certificates.
