Problem with the WebClientSSL example

[Spiridusu]

I have an Mega conected to a Esp8266 and I'm trying to run the WebClientSSL example but I get the following error:

[WiFiEsp] Initializing ESP module
[WiFiEsp] Initilization successful - 1.5.4
Attempting to connect to WPA SSID: xxx
[WiFiEsp] Connected to xxx
You're connected to the network
SSID: xxx
IP Address: xxx.xxx.xxx.xxx
Signal strength (RSSI):-562 dBm

Starting connection to server...
[WiFiEsp] Connecting to www.google.com
[WiFiEsp] >>> TIMEOUT >>>
[WiFiEsp] >>> TIMEOUT >>>
[WiFiEsp] No tag found

Disconnecting from server...

All I have changed are the ssid and pass, the Serial1.begin(9600); to Serial1.begin(115200); and the pins that I have conectad the Esp8266 from pin 6 and 7 to pin 18 and 19.
