Running Ignition v8.1.4.

Am having issues connecting a new Kepware OPC UA connection to the gateway. Followed steps on connecting Kepware from Inductive University video. When trying to establish the connection on the server that is hosting Kepware, certificates do not automatically appear. The error message that appears when I check the status of under Status \> Connections \> OPC Connections is as follows:

"UAException: status=Bad\_ConnectionRejected, message=io.netty.channel.AbstractChannel$AnnotatedConnectException: Connection refused: no further information : BMS-PRY6A-FTS1B.PRYS3.FACILITIES/172.22.10.231:49320

Appreciate any help/advice, thanks!

This is just a networking error.

First thing I'd check is whether the firewall on the Kepware machine has a rule to allow inbound TCP on port 49320. Then check to make sure Kepware's OPC UA endpoints include the network adapter for that IP address and not just localhost.
