I have it working at the moment by replacing: void sendToPushingBox(String devid) with void sendToPushingBox(char devid[]) although I think both should work fine. It also worked before with String, and when I send exactly the same text to serial, I se it 100% correct as it should be. Anyway it seems to work now. Reply from the server is OK as well.
I don't need to put all Serial.prints on 1 line, it works as the api-example as well. I have the impression that somewhere in Ethernet.client something is a bit unstable.
The issue I have now is that mails arrive only after several hours. I asked people from Pushingbox how this is possible. Before it was instantanious.

I'm having exactly the same issue. Sometimes it works for days. Then it stops working or only few mails go through.
Each time the Arduino reports a correct connection. When I try with cURL or with a browser, it works OK.
I tried a lot of different things:
- another Arduino and Ethernet card. Network is OK on both, I can brwse to them perfectly (they're server as well).
- putting \r\n as end of line instead of just \n
- change #define to const String..., but this is just cosmetics
- start the card with or witout mentionning dns, gateway. No difference.
Here the code:
void sendToPushingBox(String devid){
    Serial << F("Connecting to PushingBox") << newLineSerial;
  if (client.connect(serverName, 80)) {
    #ifdef DEBUG_SERIAL
        Serial << F("client connected to PushingBox") << newLineSerial;
        Serial << F("client NOT connected to PushingBox") << newLineSerial;
      Serial << F("sending GET request") << newLineSerial;
    Serial << F("GET /pushingbox?devid=") << devid << F(" HTTP/1.1\r\n");
    Serial << F("Host: ") << serverName << F("\r\n");
    Serial << F("User-Agent: Arduino\r\n");
    Serial << F("\r\n");
    client << F("GET /pushingbox?devid=") << devid << F(" HTTP/1.1\r\n");
    client << F("Host: ") << serverName << F("\r\n");
    client << F("User-Agent: Arduino\r\n");
    client << F("\r\n");
  else {
    Serial << F("PushingBox connection failed") << newLineSerial;
  // if there are incoming bytes available from the server, read and print them:
    if (client.available()) {
      char c =;
      Serial << c;
    Serial << F("disconnecting") << newLineSerial;

Here the debug-info:
Setting up Ethernet card
Ready, delay 5 sec to setup Ethernet card
Connecting to PushingBox
client connected to PushingBox
sending GET request
GET /pushingbox?devid=vDCC7D695F4F8672 HTTP/1.1
User-Agent: Arduino


I guess it's more a network issue, but I can't put my hands on it. Does someone have an idea? If not I'll need to put a sniffer to see what exactly is going over the network.
