Hi friends.

I have a problem when I’m using Ignition 8.0.2.

I’m trying to connect Ignition designer with the server and ModBus ModRSsim, but I can’t communicate with OPC-UA. Since I installed Ignition server and I see the Status, OPC connections has a connection Faulted, like this picture:

The log of the problem is:

Can you upload your full wrapper logs? It looks like the loopback connection to Ignition’s own OPC UA server isn’t working. Most commonly this is because there was a port conflict and the server failed to bind during startup.

Hi, Kevin.

I’m using the preinstalled OPC-UA Connection. Since I seek the endpint discovery:

Sorry, that’s not helpful. You’ll need to upload the full logs file.

You can download it from the gateway status area: [https://docs.inductiveautomation.com/display/DOC80/Gateway+Diagnostics#GatewayDiagnostics-Logs](https://docs.inductiveautomation.com/display/DOC80/Gateway+Diagnostics#GatewayDiagnostics-Logs)

or get the wrapper.log files out of the install dir.

I’m having the same issue, tried update the gateway and after uninstalled deleted the installation folder and installed ignition again, the error continues. Searched if there is some application using the port 62541, but it is free.
