Why I´ve got an error when I want fill out the form from an App?

The link in the App is correct but JOTFORM shows up some error.

I really like using JotForm but in this case I need to make it possible interact with an App.

Please help me. 

I checked your form and it is loading on my end:

https://form.jotformeu.com/angelortiz/reunion

Your form should be functional at this time.  I am not sure how your app is loading the page so I cannot test on my end.  If it is still not loading on your end, let us know how you are loading the form in the app and we will see what we can do.

Thanks for your fast answer. I´ve loading the form into the app through a link embebed in one screen.

When the app is in the phone and clck over the link pops up the error.

I´ve loaded the App like a demo in the phone and either can´t have the link to send you a QR to download the App. so I don´t know how you can help me.

Try loading from the direct URL instead of the custom URL:

http://www.jotformeu.com/form/71082548516357

The form does work from both the custom URL and from the regular URL on my end, I am not sure what is being changed in your app to prevent it from doing so.
