Ionic Framework Ionic Angular

I am getting below error, when trying to call a https request in ionic 4 app on iPhone.
And server SSL certificate is a valid and trusted one. Does any one knows a fix for this?
Thanks.

Did u try installing the whitelist plugin ?

npm i cordova-plugin-whitelist

5

Does your config.xml has allow-navigation tags?

6

Yes, I did. Same issue.

7

Yes, I already have them.

8

If you do ionic serve then on browser does the API call work?

9

Yes, it works. Working in android device also. Issue is only in iPhone.

How are you taking the build? are you uploading to Apple test flight and testing? or if you are taking adhoc build or from xcode you are directly running by connecting your phone, see the xcode logs, that might reveal something. Are you in skype? i can help out there (issue seems interesting)

Just to check if it the issue with ios or your API backend, can you try making a GET call to this API https://reqres.in/api/products/3 see if that works
