It seems like the issue is not with your API since you said it is working with cURL.
And since your second console.log() was never executed, my guess is that there is an issue with your request. Maybe you're not including required headers, etc. In your this.http.get(url), you're not including any headers. Does your API require headers to be sent? It would help if you could give your exact cURL command you used because then we could figure out what you're not including in your request.
