NodeMCU & Wemos D1 mini still cannot perform OTA upload

I have been following the steps as outlined in this OTA tutorials.
http://esp8266.github.io/Arduino/versio ... dates.html

Using BasicOTA.ino , I have set SSID, Password, upload via serial and gotten IP address via serial monitor successfully. I am able to find the OTA port after uploaded via serial.

My termite error log is as below:
Start
Progress: 0%
Error[2]: Connect Failed
Error[4]: End Failed

I have used different ESP8266 nodemcu and wemos rf mini. Both are working boards for other non-OTA programming. I used 2 different laptops and also tried my phone hotspot instead of home WIFI.

How can I debug the connection error? Is it the port limit? I have comment off to turn on the port definition and password. The authentication works until I see the connection errors.
