Hello Everyone,

I am new to Ignition Dockers. I have setup two Ignition Gateways within a docker container. I have tried connecting the Ignition Gateways via OPC-UA to Kepware on my laptop in order to setup a testing environment. However, I am not able to connect as I receive the below error.

UaException: status=Bad\_ConnectionRejected, message=io.netty.channel.AbstractChannel$AnnotatedConnectException: Connection refused: /192.168.1.95:49320

I have tried changing my OPC UA server settings and the bind address to 0.0.0.0. I have the trust certificates in both Kepware and the the Ignition Gateway enabled. I opened the Windows firewall port 49320 on my laptop for Kepware.

How can I connect to Kepware via OPC UA using a Ignition Gateway from a docker container?

Thank you for your help everyone,

You shouldn’t need to adjust the bind address for the OPC-UA Server within Ignition to make the outbound connections to KEPServerEx. For the endpoint URL, I’d use `host.docker.internal` (more info in the Docker Docs [here](https://docs.docker.com/desktop/windows/networking/#use-cases-and-workarounds), specifically the section: _I want to connect from a container to a service on the host_) to resolve to your host system. It looks like `192.168.1.95` is actually the IP address of your Ignition Gateway container, not the IP address of your host system.
