Unable to get Nest cameras

I have successfully authenticated (through integrations using Nest PIN) the Home Assistant Nest component to Nest (created developer account, retrieved clident_id + secret) and created the following in my configuration.yaml

nest:
  client_id: !secret nest_client_id
  client_secret: !secret nest_client_secret

The log shows multiple entries of the following three lines.

2018-11-11 21:13:49 INFO (SyncWorker_2) [nest.nest] Open data stream
2018-11-11 21:13:49 DEBUG (SyncWorker_2) [nest.nest] >> STREAM https://developer-api.nest.com/
2018-11-11 21:13:49 DEBUG (SyncWorker_2) [nest.nest] Exception occurred in processing stream: ('Connection aborted.', RemoteDisconnected('Remote end closed connection without response',))

As per the instructions I have opened port 9553. Cameras do not show up in Home Assistant. Anyone a suggestion on what I am doing wrong.

After a day, without any change on my part camera started to show up in HA.
