Custom Web API with error "The website or service provider you are trying to reach does not support HTTPS requests."

I’m trying to call my own web api, but I always get the error message “The website or service provider you are trying to reach does not support HTTPS requests.” although I have set https already. My API link is https://wiiwit.freehostia.com/mycontact/.
I have already tested via the browser and postman. It both worked.

Below is what I have done.

And here is the result:

Please help me.

Check how the app works in Live on your device.

It turns to Thunkable’s first screen after displaying the app home screen. :frowning:

So WebApi works in Live?

Before, no, it didn’t work in website nor device.

But now, it works whereas I have changed nothing in my API. I don’t know why. So weird.
