External Networking from Hassio with Telegram, Pushbullet, or anything appears broken


I cannot seem to hit any external addresses from Hassio – so Telegram, Pushbullet, etc don’t work at all.

I have flashed Hassio to new memory card (twice over a few days).
I have double-checked static IP address and DNS are set in Resin boot (as well as my router), but I cannot seem to hit any external address from Hassio.

Local ping test to Google.com resolve networking just fine.

Only error message is: Unable to find service notify/mytelegram

I have tried to SSH to the local docker image, but cannot seem to get public/private key configured properly.

hassio: 0.67.1,
hass.io supervisor: 0.101
Host Pi3, resinos: v1.3

Thank you in advance,

I am experience a TON of connection problems as well. No idea what is causing it. To make things worse (from a troubleshooting side) is that connections are OK some of the time.
The logs show many errors start with the following exception.

Traceback (most recent call last):
  File "/usr/lib/python3.6/site-packages/urllib3/connection.py", line 141, in _new_conn
    (self.host, self.port), self.timeout, **extra_kw)
  File "/usr/lib/python3.6/site-packages/urllib3/util/connection.py", line 83, in create_connection
    raise err
  File "/usr/lib/python3.6/site-packages/urllib3/util/connection.py", line 73, in create_connection
OSError: [Errno 101] Network unreachable

I am running hass.io in a Linux VM.
