We have upgraded our system to Ignition 7.8.2, 2 month ago.  
We encounter some trouble with opc-ua settings for client connection,  
Our gateway is redundant.

We have to set on each gateway a local opc-ua connection to an opc-au siemens server.

When we configure the connection on master side,  
with opc.tcp://localhost:4845, and press Discover,

We obtain :  
opc.tcp://GTC-N-EST:4845  
SecurityPolicy: Basic128Rsa15, MessageSecurity: SignAndEncrypt  
opc.tcp://GTC-N-EST:4845  
SecurityPolicy: None, MessageSecurity: None

It’s ok for the MASTER, we use SecurityPolicy: None, but the connection on the BACKUP node is not the same ! … but these settings are sync between MASTER and BACKUP gateway !  
(must be : opc.tcp://GTC-S-EST:4845 on the BACKUP side)

Any Idea? host override has no effect…

This is fixed in 7.8.3 with additional settings for configuring the backup node.

I think it’s supposed to get uploaded today. Myron should have emailed you a download link by now.

Perfect, as soon as I received a download link, we will upgrade to 7.8.3b our test platform to check the fix, and post back here, or a PM if all is fine or not.
