Hello,
From your answer 2 I assume you are trying to connect to http://localhost/127.0.0.1:1234 with some HTTP client (e.g a web browser), that request will not be served by the OPC-UA server but by the embedded Jetty web server instance.
If a request fails with code 2150891520, it should mean that you are trying to access a node that does not exist on the server (a node with the requested id cannot be found by the server).
The good news is that the fact that you can see this error implies that the driver was able to successfully connect and authenticate with the server, so firewall and global driver settings should be ok.
The next step is configuring asset channels.
For this purpose, I would suggest you to try connecting to the OPCUA server with a graphical OPCUA client (e.g a desktop or smartphone app), browse the server nodes with that and determine the the ids of the nodes you are interested reading/writing.
Once you discovered these node ids, you can use that information to configure the OPCUA driver channels.
I'm sorry but I cannot provide support for the tutorial you mentioned, as it is related to a commercial product.
Regards,
Nicola

Hello Nicola,
Thank you so much for your valuable suggestions, now I able to getting the data in data tab of opc-ua driver but one thing i want to ask for h2db service i created h2db server but i am not able to access the server in my web browser, This is the document which i am following-->https://eclipse.github.io/kura/builtin/h2-database.html
The kura is install in my device i connected it through wifi ip, but i am not able to access http://192.168.42.5:9123/
I checked firewall connection also, i change this -webPort 9123 -webAllowOthers -ifExists port to 9124 but result is same
Please give me some hint about this and thank you again for your quick reply.
Thanks and Regards,
Abhi

Hello,
I wouldn't know what's going on.
Configuring the firewall to allow TCP connections to TCP port 9123 and configuring the DbServer instance as follows should be enough:
db.server.enabled -> true
db.server.type -> WEB
db.server.commandline -> -webPort 9123 -webAllowOthers -ifExists
You can check if the server is listening on port 9123 by running curl directly on the device, try the following command:
curl http://localhost:9123/
If curl is not available you can try the wget, or try installing it.
If you get a response like the following, then the server is up and running:

If the curl test succeeds, then there might be something wrong with the firewall. Otherwise, do you have other services using port 9123?
Regards,
Nicola
