I know this might seem to be a duplicate problem but I search for hours here and didn't fine any solutions working : Here is my problem, when I use my app sometimes request are not working, it comes more often when I run it on a iOS devie (iPhone 5s) than it does on an Android device (One + 5T). When I try to request the api I got the following errors. And : `
[Error] Erreur de récupération des gameCredits – e {headers: t, status: 0, statusText: “Unknown Error”, …}
e {headers: t, status: 0, statusText: “Unknown Error”, url: null, ok: false, …}e

I tried the answers I found on the following discuss : - IONIC 3 CORS ISSUE (setting proxy) - CORS error in Ionic 3 (downgrading to UIWebview) - Adding an to everything in my config.xml - I added the headers in my authentification service to make sure they were present - I added the headers to send them back in the API.
Do you guys have any idea of how I can solve this problem?
Here are some examples of my code : This is the post example of how I request my api
post(url: string, body?: any) {
return this.checkToken().then(isTokenValide => {
if (isTokenValide) {
return this.getToken().then(
token => {
this.headers = this.headers.set('Authorization', 'Bearer ' + token);
return this.http.post(this.domain + url, body, { headers: this.headers }).toPromise()
.then(response => {
let httpResponse = new HttpResponse(response);
if (this._checkStatus(httpResponse))
return Promise.resolve(response);
}).catch(error => {
return Promise.reject(error);
});
},
error => {
return Promise.reject(error);
}); } else {
if (url == 'auth/login' || url == 'auth/register') {
const headersLogin = new HttpHeaders({'Accept':'application/json','Content-Type':'application/json'});
let loginUrl =this.domain +url;
return this.http.post(loginUrl, body, { headers: headersLogin }).toPromise()
.then(response => {
let httpResponse = new HttpResponse(response);
if (this._checkStatus(httpResponse))
return Promise.resolve(response);
}).catch(error => {
return Promise.reject(error);
});
} else {
return Promise.reject('token invalide');
}
}
}).catch(error => {
return Promise.reject(error);
});
}
