eWeLink Bridge eWeLink WARNING WS login failed as WebSocket closed with reason: undefined
### Details of your setup.
* Do you use (1) Homebridge UI-X (2) Homebridge CLI or (3) HOOBS? 

I am currently using HOOBS with the ewelink plugin where every so often I see this in the logs

eWeLink BridgeeWeLinkWARNINGWS login failed as WebSocket closed with reason: undefined (undefined). at WebSocketAsPromised._handleClose (/var/lib/hoobs/ewelinkbridge/node_modules/websocket-as-promised/src/index.js:407:19).

and control of my ewelink devices from homekit/hoobs does not work until I restart the plugin or hoobs. The problem goes away for sometimes, hours or days but comes back again. 

I am running Hoobs v4.3.0 on a Pi 4 and I am running v 12.1.0 of the ewelink plugin.
