Hi,

how to implement a OPC auto-reconnect pattern ??

Thanks

After I Clone the project and run it .the local page appear

How can I fix it, I just newbie to research about OPCUA webplatform.

I am using the UA sample Server or NetCoreConsoleServer (https://github.com/OPCFoundation/UA-.NETStandard ), when I run the project in the Visual Studio,It can connect the Server and read values well. But When I Publish it , when I run OPCUA_Web_Platform.exe by itself, or I run the service through IIS , it shows "DataSet Not Available".
I've been suffering this problem for 5 days.
So could u describe "Troubleshooting-You may occur in error like "DataSet Not Available" even if all the ip addresses or your OPC UA Server are perfectly configured. Be aware you have configured the platform Instance Certificate in the OPC UA Servers Trusted certificate store." more clearly ?
I'm wondering how to configure the platform Instance Certificate in the OPC UA Servers?
I'm very appreciate If u can provide a example, or show me the way where to find the solution.
thanks.

I started the Monitor using http://{{base_url}}/api/data-sets/{{dataset-id}}/monitor
and I used a HTML javascript code...

ws = new WebSocket(url);
url = signalr:http://localhost:8080

and I´ve got
Uncaught DOMException: Failed to construct 'WebSocket': The URL's scheme must be either 'ws' or 'wss'. 'signalr' is not allowed.

Do you have an exemple of javascript code to receive monitored data?

Thanks.

Hello, when i run the application, "An unhandled exception occurred while processing the request"

It seems like that "System.NullReferenceException:“Object reference not set to an instance of an object.”

if (context.Request.Path.StartsWithSegments("/api"))
            {
                string authorization = context.Request.Headers["Authorization"];
                string token = "empty";

                if (authorization.StartsWith("Bearer ", StringComparison.OrdinalIgnoreCase))
                {
                    token = authorization.Substring("Bearer ".Length).Trim();

authorization is null
what should I do to solve this problem, I would appreciate it.

Hi,

I can see that you are using "OPCFoundation.NetStandard.Opc.Ua", this package is under GPL 2.0 if you aren't a member of the OPC foundation.

http://opcfoundation.github.io/UA-.NETStandard/

Wouldn't that make your repo GPL 2.0 as well?
