Hello  
I setup OPC UA server of ignition as below:

 ![opc%20ua%20setup](https://us1.discourse-cdn.com/inductiveautomation/original/2X/3/3c938cdab16e43c04fed2a70b79238b777ad1ac0.jpeg)  
But when I try to define new OPC client connection (opc.tcp://localhost:62541/discovery) in ignition I get internal error:  
 ![image](https://us1.discourse-cdn.com/inductiveautomation/original/2X/6/6c924d5e59c28905030dd0cb6925afc2578fc3b2.png)  
and this one when use opc.tcp://10.3.141.1:62541/discovery. The 10.3.141.1 is my IP address of the network card.  
 ![image](https://us1.discourse-cdn.com/inductiveautomation/original/2X/f/fe4f59b505c17a3d629332e7b72819b9b9f07df0.png)

This happen after I try to enable expose tag in ignition OPC UA server.  
I use v8.0.6RC1.

Can you go to the gateway logs and see what error is being logged when you get that ‘Internal Error’ page?

You need to add that IP address as a Bind Address as well.

edit: or, better if you intend to allow connections from other machines, just use 0.0.0.0 as a bind address.

Hi

Did you fix the “Bind Addresses” setting for the OPC UA server and restart yet?

No, first I did reset and every thing working for now. and after that I add that.  
This problem happens today two time for me, specially after reset the device.  
I As docs said IA make discovery extremely hard compare to 7.9.  
I will update post if this problem happens again.

Is your devices IP address changing or something? I'm not sure I understand what you're doing to trigger this.

If this is an OPC UA connection to the local server why are you using anything but localhost?

No it’s dedicated.

I use both. I try to connect ignition to node red in Raspberry PI locally and I see some difficulty so I try first connect first ignition to kepware Opc UA client on another computer. At this time after I reset my device I notice the internal OPC UA connection that is made default my ignition is faulty.  
May this because of missing bind address.  
Now it work for the time.
