# Bug Report

### Describe the Bug
About a month ago, I started getting HomeKit not being able to reach the Ring Pro video.  I had stayed on an older version of the plugin for a long time. I decided to upgrade to latest (and generated a new refresh token).

Every 5 seconds I get this:
8/30/2021, 1:09:21 PM [Ring] Failed to reach Ring server at https://oauth.ring.com/oauth/token.  connect ECONNREFUSED 127.0.0.1:443.  Trying again in 5 seconds...

I saw a similar error, but not with trying to connect to 127.0.0.1:443.  I don't know why it's trying to do that.

### To Reproduce
Install homebridge-ring 9.21.0  via HOOBS.
Create refresh token and add to configuration.
Save to restart HOOBs/homebridge. Get repeated errors.  Persists after Pi reboot.

### Expected behavior
normal functionality without error.


### Screenshots/Logs

### Additional context
I have removed and re-added plugin, I have tried earlier versions of plugin.  Each version has some other odd problem.  Ultimately it's not working anymore with this consistent reproducible error now.

### Homebridge Ring Config
```

        {
            "refreshToken": "myTokenHere",
            "sendCameraMotionNotificationsToTv": true,
            "plugin_map": {
                "plugin_name": "homebridge-ring"
            },
            "platform": "Ring",
            "hideDeviceIds": [],
            "locationIds": [],
            "onlyDeviceTypes": []
        }


```

### Environment

 - OS: Raspbian
 - Node.js: v12.14.1
 - NPM: 6.13.4
 - homebridge-ring: 9.21.0
 - homebridge: ?
 - hoobs: 3.3.12

Any help would be appreciated so I can use Ring again with my iOS devices and AppleTV.
