okhttp3.internal.http2.StreamResetException: stream was reset: PROTOCOL_ERROR/ CANCEL

I am connecting to web service with last version retrofit but get me bellow error :

okhttp3.internal.http2.StreamResetException: stream was reset: PROTOCOL_ERROR

My code is like bellow :

try {
                    // Create a trust manager that does not validate certificate chains
                    final TrustManager[] trustAllCerts = new TrustManager[]{
                            new X509TrustManager() {
                                @Override
                                public void checkClientTrusted(java.security.cert.X509Certificate[] chain, String authType) throws CertificateException {
                                }

                                @Override
                                public void checkServerTrusted(java.security.cert.X509Certificate[] chain, String authType) throws CertificateException {
                                }

                                @Override
                                public java.security.cert.X509Certificate[] getAcceptedIssuers() {
                                    return new java.security.cert.X509Certificate[]{};
                                }
                            }
                    };

                    // Install the all-trusting trust manager
                    final SSLContext sslContext = SSLContext.getInstance("SSL");
                    sslContext.init(null, trustAllCerts, new java.security.SecureRandom());
                    // Create an ssl socket factory with our all-trusting manager
                    final SSLSocketFactory sslSocketFactory = sslContext.getSocketFactory();
                    OkHttpClient.Builder builder = new OkHttpClient.Builder();
                    builder.sslSocketFactory(sslSocketFactory, (X509TrustManager) trustAllCerts[0]);
                    builder.hostnameVerifier(new HostnameVerifier() {
                        @Override
                        public boolean verify(String hostname, SSLSession session) {
                            return true;
                        }
                    });

                    OkHttpClient okHttpClient = builder.
                            build();
                    Retrofit retrofit = new Retrofit.Builder()
                            .baseUrl("https://xxx")
                            .client(okHttpClient)

                            .build();
                    final PublicApi request = retrofit.create(PublicApi.class);
                    Call<GetStatusSaveContactListModel> call = request.sendContactLists("saveContactList", obj.toString());
                    call.enqueue(new Callback<GetStatusSaveContactListModel>() {
                        @Override
                        public void onResponse(@NonNull Call<GetStatusSaveContactListModel> call, @NonNull Response<GetStatusSaveContactListModel> response) {

                    throw new RuntimeException(e);
                }

And

                                                     @Query("data") String data);

This is happening to me in production, but I am not able to reproduce the problem when debugging

Have we got any update on this? I get this when i trigger a specific api in quick succession for example: API called API called again (before i could get response) throws StreamResetException

but if i call the API wait for some time i get the response API called . . . waiting . . after some waiting finally i get the response
