Ajax fails when making request to sub-domain

I am opening in appbrowser with this code:

`const browser = this.iab.create('https://www.example.com/login/','_blank',{location:'no'});`

inside login page there is an ajax to this url:

**https://search.example.com:3000/zip/?keyword=1235**

It is working fine with browser, but on real device it cancels automatically, here are screeshot while live debugging on real device


Reproduce the `this.iab.create` call on a real device and compare it with browser behavior, recording the device platform and the AJAX cancellation details. The report names no source file or test; done means identifying the cause of the cancelled request to the sub-domain on port 3000 and documenting a reproducible result.
