Why doesn't socket.getaddrinfo work in micropython (esp8266) but does in python string?

Question

Internet of Things

This code does not work on esp8266, but works in normal python:

>>> addr = socket.getaddrinfo('smart-socket-bdcc5.firebaseio.com', 443)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
OSError: -2

That being said, other variations of socket.getaddrinfo work, for examplesocket.getaddrinfo("towel.blinkenlights.nl", 23)

Answer 1

The reason was simple: wrong wifi password
