OPC Connection to remote OPC UA Server V8.1.20

Ignition
1

We are trying to connect to a remote OPC server. The local address is 10.4.200.17 (where the gateway is running). The remote device is at 10.4.223.1. All devices can be pinged, and we have other connections from the gateway to the device. Just need to set up an OPC UA for some points. We have tried a lot of combinations, but we continue to get a connection rejected. We have tried different security including no security. We don’t have any rejected certs in the folder. The connection just rejects with the message.
UaException: status=Bad_ConnectionRejected, message=io.netty.channel.AbstractChannel$AnnotatedConnectException: Connection refused: no further information: /10.4.200.17:62541/discovery:
All ports are open on both devices.
This is from the log file
java.util.concurrent.ExecutionException: UaException: status=Bad_ConnectionRejected, message=io.netty.channel.AbstractChannel$AnnotatedConnectException: Connection refused: no further information: /10.4.200.17:62541

Any help would be appreciated.

This is a network-level error. Think firewalls or the remote side isn’t listening on that host/port combo.

Is the remote server another Ignition Gateway or is it a 3rd party server?

Thanks for the ideas Kevin. The device is a Honeywell Jace 8000. I did some testing with Wireshark on the system. The OPC server in the Jace port is set to 62541, the same as the endpoint discovery. I used Wireshark to do a capture. It looks like the request is coming from the Gateway to the Jace, and the Jace is replying to the request. I am getting this message when it fails: UaException: status=Bad_ConnectionRejected, message=io.netty.channel.AbstractChannel$AnnotatedConnectException: Connection refused: no further information: /10.4.223.29:62541

It looks like the ports are now open, but for some reason the connection is refused. WE are not getting a rejected cert in the folder. We have tried different security settings, and confirmed the username and password.
Any other ideas would be appreciated. Thanks!

You have the same issue as your original post, only the IP address seems to have changed. Still something outside of Ignition. Your capture shows the TCP connection being shut down by the server or something in between.
