Hello everyone, I am trying to integrate JACE8000 data over OPC UA into Ignition software. However, I came across an issue (see below). Are someone familiar with similar problem ? OPC UA connection is working with a third party OPC browser and JACE8000. So I guess, the issue in not on the JACE8000 side.

The `Bad_InternalError` StatusCode is coming from the server. A Wireshark capture might help if you’re able to configure the connection without security. Maybe two captures, to compare between a client that can connect and Ignition. Otherwise you’ll have to get in touch with support from whoever makes this server. ---

Hello Kevin, This is the Wireshark capture from Ignition to JACE8000 PC (Ignition) sends UA Secure Conversation Message: FindServesrRequest and getsUA Secure Conversation Message: FindServersResponse. ![Ignition_and_JACE8000](https://us1.discourse-cdn.com/inductiveautomation/original/3X/9/f/9f5464dc3ae67e4f322f8c7a30ba4f4dc9ae45bb.png) And this is Wireshark capture from third party software and JACE8000 The third party software exchanges the ApplicationInstance certificates with JACE8000. ![Thirdparty_and_JACE8000](https://us1.discourse-cdn.com/inductiveautomation/original/3X/6/d/6dc00a0d51e2dd60bc8648ca713414ac62c127fd.png) ---

Can you upload the capture files? ---

I think this capture is incomplete. After the FindServers exchange there is nothing but unprompted Error messages from the server. I think this may be because the discovery URL returned by the server is `opc.tcp://127.0.0.1:52520/OPCUA/N4OpcUaServer` and your capture filter did not include localhost. Can you try again to see if you can get the full exchange? ---

Sorry, but this capture is the same: ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/4/f/4f7c7898c46c2acb2c3df7ad588f8bf1e77d1921.jpeg)
