I am having trouble with my local blynk server. I can’t get my ESP8266 to connect. I am using the blynk demo and can connect to the blynk server, but not to my raspberry pi server. I can see that the ESP8266 is connecting to the wi-fi, but it never shows as connected when I watch from the server administration browser and it shows as disconnected on the app. I can see the app has connected to the server, and have checked the authentication token several times to ensure it is correct. I believe the error is somewhere in my server setup, but I am not sure where to start looking. I have been through the log, but have not seen anything. Unfortunately I am having trouble getting the log off the raspberry pi. Code I’m uploading via Arduino is below. Pretty sure it doesn’t matter but the ESP8266 is the Adafruit version.

*************************************************************
You’ll need:
- Blynk App (download from AppStore or Google Play)
- ESP8266 board
- Decide how to connect to Blynk
(USB, Ethernet, Wi-Fi, Bluetooth, ...)
There is a bunch of great example sketches included to show you how to get
started. Think of them as LEGO bricks and combine them as you wish.
For example, take the Ethernet Shield sketch and combine it with the
Servo example, or choose a USB sketch and add a code from SendData
example.
