Cant connect to Firebase from my Raspberry pi

Question

I'm having some issues with my raspberry setup.

The test:

# -*- coding: utf-8 -*-
import requests
import json

firebase_url = 'https://myDb.firebaseio.com'
name = 'db_name'
test = {}
print(firebase_url + '/' + name + '/setup.json')
test = requests.get(firebase_url + '/' + name + '/setup.json')
test = test.json()

print(test)

Runs on my laptop with no problems. On the Raspberry Pi I get this:

https://myDb.firebaseio.com/db_name/setup.json

I get that it means that it can't connect. Why it can't connect is another question though. I'm running this test while logged in over SSH with weaved . So internet is up and running without any problems. I feel like I'm missing something obvious but I just don't know where to look.

Thanks!

Answer 1

It was a DNS problem and everything was fixed by adding nameserver 8.8.8.8 to /etc/resolv.conf...

Case closed.
