Problem/Motivation

After updating HA from (I believe) 0.108 to 0.111.4, Node Red no longer works. All the nodes are stuck on “connecting”, and the Node Red add-on’s log keeps repeating the following over and over after getting through all the startup stuff:

19 Jun 22:59:58 - [info] [server:Home Assistant] WebSocket Connecting http://supervisor/core

It just keeps repeating that and never stops.

I’ve tried:

1. Updating the supervisor (now on version 227) and Host os (now on HassOS 4.10)
2. Rebooting the server
3. Updating Node-Red add-on to the latest version (now on 6.3.0)
4. Changing the credential_secret to something else, starting the add-on, then changing it back (someone said this might work…it didn’t)
5. Resetting the Node-Red add-on’s config to default (only changing my credential_secret back to what it was)
6. Exporting all my flows, uninstalling the NR add-on, and re-installing.
7. Un-checking "I use the Home Assistant Add-On" option in the Home Assistant configuration node, saving and then re-checking it and saving again.

None of the above had had any effect. Since all my home's automations are done in NR now, my house is totally dumb at the moment.

I haven't observed any other connection issues to Home Assistant. My mobile app works, Alexa works. Only NR seems to be having an issue.

Expected behavior

Node Red can connect to HA.

Actual behavior

Node Red log shows never-ending "WebSocket Connecting http://supervisor/core" message

Steps to reproduce

Unsure; I am on HA 0.111.4 and Node-RED add on 6.3.0. I don't think I have anything particularly weird with my setup, I'm using all official add-ons. NR has worked fine for over a year.
