"Http failure response for (unknown url): 0 Unknown Error" Angular
18,811
From what I can see, it's not an error from the http client directly, but from your server.
In a similar issue, the problem was coming from CORS and the fact that the Access-Control-Allow-Origin header was not correctly added in case the server response did not have a 20X or 30X status.
Did you check your server and log the call ?
Hope that helps
