Problem with external link [net::Err_FAILED]

I have problem with my app (realase) - I connect to my app external payment method, when i Click payment, i am redirect to external page (payment operators). When I click on operator website on link i get Application Error:

Application Error

When I Click ok on this error alert My App is close and go to try. When I open from try My website run from home page.

What is wrong?

When I debug on dev console - i don’t get error - only on mobile devices i get error alert.

I will be very grateful for help …
