[WebApp] Hello World Web App
I installed the example on my windows2008 VPS.
The example is working fine from local (127.0.0.1:51042) , but CALCULATE button is not response and not shows any result when accessing remotely.

Do these examples work properly when you test them from the computer: https://b4x.com:51041/ ?

Can you post a link to your VPS?

Works fine here.

Use a tool such as Firebug to see whether there are any errors.

Yes. Use Chrome development tools to understand what is not working.

Hi Erel,
Kindly check the below image , Any idea?

 

[Erel]

No, it is not relevant. I tested your link with Chrome and it works fine here.

It is probably a network issue between your computer and the server. A proxy in the middle can break the WebSocket connection.

Do you recommend to build web applications using websockets? or should I looking for any other approach?

Thank you & Best Regards

Do you recommend to build web applications using websockets?

Yes. Many developers use it successfully. You need to investigate why it doesn't work with your server.
