EK-TM4C1294XL: Ethernet server does not accept clients after first power-on.

Part Number: EK-TM4C1294XL
Other Parts Discussed in Thread: ENERGIA

I'm using latest version of Energia IDE. I'm having problem with ethernet controller of this card. First time i power-on card and try to connect to ethernetserver on card by using a tcp client on my pc i can't connect. I can read "SetupCompleted" on serial port output, but code just stops executing at "client = server.available();"

If i use the reset button on card, i can connect.

How can i fix this? 

Edit: After first time i power-on the card, if i re upload code to card using energia; again i can connect to ethernetserver of card.

void setup()    
{   
  //Start Serial Port
  Serial.begin(9600);
  delay(1000);

  while (!Serial) {
    ; // wait for serial port to connect. Needed for native USB port only
  }

 if(EEPROM.read(EEPROM_ADDRESS_ISFIRSTRUN) == 0xFF) //First Run
 {
    ...
    //Writing something on EEPROM here.
 }
 else 
 {
    ...
   //Reading something from EEPROM here.
 }
 
  ethernetSettingsIsSet = EEPROM.read(EEPROM_ADDRESS_SETTINGISSET);

  if(ethernetSettingsIsSet != 0xFF) //User set ethernet configuration before.
  {
    ...
    //Read ethernet configuration from EEPROM
  }
  else //Defaults
  {
    //do nothing
  }

  //Start Ethernet
  server = EthernetServer(PortNo);
  Ethernet.begin(Mac, Ip, Dns, Gateway, Subnet); 
  delay(1000);
  server.begin();
  delay(100);


  Serial.write("SetupCompleted");
}

void loop() 
{ 
  delay(5);

  client = server.available();

  if (client)
  {
  
    if (client.available()) 
    {

      ...
      ...
      ...     
      
      client.stop();
      delay(10);
    }
  }

  delay(10);
  if(Serial.available() > 0)
  {
    
      ...    
      
  }

   delay(10);
}
