# Bug Report

### Describe the Bug
<!-- ✍️edit: --> I'm not able to reach Ring server.

### To Reproduce
Steps to reproduce the behavior:
 - Start Homebridge
 - Attempt to view ring camera feed
 - See 'no response'

### Expected behavior
<!-- ✍️edit: --> A clear view of the ring doorbell.


### Screenshots/Logs

Failed to reach Ring server at https://oauth.ring.com/oauth/token.  connect ECONNREFUSED 127.0.0.1:443.  Trying again in 5 seconds...
### Additional context
<!-- ✍️edit: --> I was getting a warning from homebridge UI saying my time was out of sync.  I ran this to get it back in sync:  
sudo systemctl restart  systemd-timesyncd
per the instructions here:  https://github.com/homebridge/homebridge-raspbian-image/wiki/How-To-Set-Date-And-Time
I'm not sure if that has anything to do with it, but could be... I think I also had an update for the ring plugin just before that as well.
I'm able to authenticate fine with 2FA and all, it just doesn't seem to be able to communicate with the server anymore.

any help is greatly appreciated.
