I'm using retrofit to make requests.

I've got following error:

java.net.ProtocolException: Too many follow-up requests: 21

The code is like below:

private OkHttpClient httpClient;
private CookieManager cookieManager;

public <S> S createCookieService(Class<S> serviceClass) {
    httpClient.interceptors().clear();
    httpClient.setCookieHandler(cookieManager);
    Retrofit.Builder builder = new Retrofit
            .Builder()
            .client(httpClient)
            .baseUrl(url)
            .addConverterFactory(GsonConverterFactory.create());

    Retrofit retrofit = builder.client(httpClient).build();

    return retrofit.create(serviceClass);
}

And then I'm making requests:

example:

1) login

 @POST("/login")
 Call<User> login();

2) some request:

@GET("/request")
Call<PojoPojo> getPojo();

And I'm getting this error too many follow-up requests: 21.

Please help.

This gets thrown (by OkHttp, not Retrofit) when there are more than 20 redirects when calling an endpoint. Usually this indicates a redirect cycle between two endpoints. Both Chrome and Firefox will also stop loading the request after this many redirects and fail the request.

You need to consult with your server team or endpoint documentation to ensure you are passing the correct data directly to the endpoint you want to call. No action for Retrofit to take here.
