Twitch Api Helix started returning an Unauthorized error

[kamiru]

In my application there are several methods using the Twitch API, I will give an example of one of them:

private async Task<TwitchStreamResponse> GetStreamInfo(string channel)
        {
            var request = new HttpRequestMessage(HttpMethod.Get, $"https://api.twitch.tv/helix/streams?user_login={channel}");
            request.Headers.Add("Client-ID", _clientId);
            request.Headers.Add("Authorization", $"Bearer {_accessToken}");

            var response = await _httpClient.SendAsync(request);
            response.EnsureSuccessStatusCode();

            var responseBody = await response.Content.ReadAsStringAsync();

            return JsonConvert.DeserializeObject<TwitchStreamResponse>(responseBody);
        }

Error example:

StatusCode: 401, ReasonPhrase: 'Unauthorized', Version: 1.1, Content: System.Net.Http.HttpConnectionResponseContent, Headers:
{
  Connection: keep-alive
  Timing-Allow-Origin: https://www.twitch.tv

  Vary: Origin

}

I didn’t change anything in the code, but at some point these methods started returning a 401 Unauthorized error.

I tried to create a new app in the twitch api console and use the new Client-ID and Authorization headers, but it did not help.

Could you tell me, please, maybe something has changed in using the API? I didn’t find any information and I can’t understand why this problem started to appear.

Is the token still valid?

Whats the body of the response?

The HTTP code is half the information.
The body should describe the fault
