No connection possible from arduino to Pusher

[01giraffe]

I can't get it to connect from arduino to pusher.
Will you help me, maybe you can find what I am doing wrong.

The situation is as follows

I have added all keys in the pusherclient.cpp. between the "" as you had described.

In the example script in IDE, I haven't changed anything, but when I compile I get the following message: Compilation error: no matching function for call to 'PusherClient::connect(const char [18])'.

When I remove the "your-api-key-here"
in the line: if(client.connect("your-api-key-here")) {

I no longer get compile errors. but get as response in the serial monitor:
21:44:16.328 -> Connecting to host.
21:44:16.328 -> Connection to host failed.
21:44:16.361 -> Connection to Pusher failed.

I suspect the error is in that if(client.connect line.

i used an arduino uno, with ethernet shield
