First thing I would check for "connection failed" is the Wifi info:

• Can your ESP8266 connect to your wifi? i.e. does the SSID and password match the one in ESP8266_PIRv2.ino (both SSID & pwd are CaSe SensiTive!)

If Wifi is good, you should see something like:
WiFi connected
IP Address: 192.168.x.x
and the LED blink 3 times.

Next is to verify the IFTTT settings:

1. Log into your account IFTTT and go to "My Applets" https://ifttt.com/my_applets

2. Select the "pirtrigger" and click on the "Check Now" and look for the email in your inbox. It can take 5-10 min to receive at times.
   

3. If that works, you can then verify the IFTTT API itself is working: Go to https://ifttt.com/services/maker_webhooks/settings and copy/paste the URL: displayed (looks like https://maker.ifttt.com/use/b8rXq5k... ) and follow the instructions to trigger the event.

4. If this is all working, then that will tell you that IFTTT is set up properly.

5. Does your IFTTT API key match the one in the ESP8266_PIRv2.ino ? (the API key is that long text string shown in step 3 above. Something like b8rXq5k... .)

NOTE: that SSL fingerprint is ONLY needed if line 58 shows bool verifyCert = true;
Otherwise it is ignored.

Most likely things: wrong API key, wrong SSID/Password
