auth basic login not working in apk

[adsonrocha]

I am using the following code to signin inside a provider:

signIn(details): Promise<any[]>{
   return new Promise((resolve, reject) => {
     this.auth.login('basic', details).then(() => {
       resolve();
     }, (err: any) => {
       reject(err);
     });
   });
 }

I have properly imported Auth at my provider constructor.
It works when I preview on browser and Ionic View, but triggers this error after install an apk generated by "ionic build android --prod":

Error: Request has been terminated. Possible causes: the network is offline, Origin is not allowed by Access-Control-Allow-Origin, the page is been unloaded, etc.

My internet connection is on.
