Hi. I have Gateway 7.8.2 running a OPC-UA connection via an OPC tunneller to Gateway v7.7.1 Every so often it disconnects and then sits saying connecting. When I disable and enable, it reconnects and says connected. Any way to get it to reconnect automatically? ---

It’s supposed to be automatic. Given the older versions in play, the first thing you should try is to upgrade each gateway to the latest version in that series. ---

I upgraded the Gateway from 7.8.2 to 7.85 successfully. I upgraded the Gateway with the OPC tunneller to v7.7.8 but now the Ignition OPC-UA server has disappeared from the OPC Server connections and then in status its showing faulted and "OPC server connection is faulted. Type “com.inductiveautomation.OpcUaServerType” is not a known server type. " ---

v7.7.7 is also saying OPC server connection is faulted. I have reverted back to v7.7.1 temporarily as its working ok ---

Any other suggestions on this? it stayed connected with data for 10 days. Then my trends began to flat lining even though OPC was saying connected. I disconnect and reconnected and it faulted with a “No anonymous token policy found” error. I re-entered the opcuauser password and it reconnected and live data again ---

Using such an old version, there’s not much we can offer from a support standpoint. I’d recommend updating to either 7.9 or 7.7.8, and if you’re having issues with your OPC-UA connection call/email in to support so we can take a look at things. ---
