Walled Garden Problems or Html Scripting Problems

Good day!

I’m working on a project for my clients where they can just fill up a form to register to my hotspot.

This is how my project my works.

  1. The client fills this form
  2. I receive the data through telegram using api’s
  3. They pay
    4.I text them their username and password

But my problem is that I cannot send the data to my telegram account when it’s in the hotspot folder in my router but when I fill up the form outside the router like the html is on my desktop (I’m still connected to the hotspot but I’m not logged in yet.) I can receive the data. Any thoughts?

This is the code below.

The sent data shows on the url tab, is this normal?
