Operating environment (Hass.io/Docker/Windows/etc.): RPi3/Raspbian

**Please provide details about your environment. Python 3.6.3/vitual_env

Component/platform: camera/synology

Description of problem: After a few days without restart/reboot when I am restarting HA or rebooting RPi at the HA startup, there is an error "session expired" and the camera isn't initiated. The next HA restart initiates the camera correctly.

Problem-relevant configuration.yaml entries and (fill out even if it seems unimportant):

camera:
  platform: synology
  url: http://SYNOLOGY_IP:5000
  username: !secret synology_user
  password: !secret synology_password
  timeout: 15

Traceback (if applicable):

I'm having the same issue on .70, but only when I added a second DSM running Surveillance Station. One DSM sets up fine and works, the other does not show camera thumbnails in the Front End, however the camera works when I click on the card.
