# Bug Report

### Describe the Bug
Since installing v9.0.0, Ring plugin is no longer able to connect to Ring oauth URL. Everything was working great in the previous version, no issues. I've unlinked account multiple times. I've uninstalled the plugin multiple times. I've restarted my routers and I've also hit the https://oauth.ring.com/oauth/token URL successfully from the Raspberry directly. It can ping oauth.ring.com as well.

Is there a way to revert back to an older version of the Ring plug to confirm that one still works?

### To Reproduce
Steps to reproduce the behavior:
 - Start Homebridge
 - Attempt to start Ring plugin
 - See error [Ring] Failed to reach Ring server at https://oauth.ring.com/oauth/token.  Trying again in 5 seconds...

### Expected behavior
It would connect to Ring oauth URL
