I want to connect Ethernet board (W5100 HR911105A) to Arduino Leonardo with SPI and I also want to connect SD reader. When I test these boards separately everything working. But when I test these devices onconnect them on the same board the program fails at Ethernet.begin();

#include <SPI.h>
#include <Ethernet.h>
#include <SD.h>

#define SS_SD_CARD  4
#define SS_ETHERNET 10

const char CONFIG_FILE[] = "system.cfg";

byte C_MAC[] = { 0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xED };
IPAddress S_IP(192,168,0,19);
IPAddress C_IP(192, 168, 0, 177);
const uint16_t  S_PORT = 8090;

EthernetClient client;

void setup() {
  Serial.begin(9600);
    while (!Serial) {
    ; // wait for serial port to connect. Needed for native USB port only
  }
    pinMode(SS_SD_CARD, OUTPUT);
    pinMode(SS_ETHERNET, OUTPUT);

    digitalWrite(SS_SD_CARD, HIGH);
    digitalWrite(SS_ETHERNET, HIGH);
    
    digitalWrite(SS_SD_CARD, LOW);
    SD.begin(SS_SD_CARD);
    digitalWrite(SS_SD_CARD, HIGH);
  
    Serial.println("Setup ethernet");
    digitalWrite(SS_ETHERNET, LOW);
    if (Ethernet.begin(C_MAC) == 0) {
      Serial.println("Failed to configure Ethernet using DHCP");
      Ethernet.begin(C_MAC, C_IP);
    }
    delay(100);
    Serial.println("connectin...");
    bool result = client.connect(S_IP, S_PORT);
    Serial.println("connected");
    digitalWrite(SS_ETHERNET, HIGH);
}

void loop() {
  Serial.println("loop...");
  delay(1000);
}

I tried on Leonardo and Mega 2560.
