Aiohttp error in supervisor logs when loading any ingress add-on

I get this error in the supervisor logs and a

500 Internal Server Error

Server got itself in trouble 

whenever I attempt to load the ui for a plugin that uses ingress (node-red, terminal)
the node red flows I have are running and controlling the system.
Has anyone seen this issue or know how to remedy or what the root cause might be?

What version of HA are you running? There was an update to aiohttp in 2023.10.2 which caused issues and was reverted in 2023.10.3. Could this be the cause?

thanks for the reply! This is what Iā€™m running:

  • Core2023.11.0
  • Supervisor2023.10.1
  • Operating System11.1
  • Frontend20231030.1

So this is a beta version of HA? Maybe there are issues not yet resolved.

EDIT: sorry see this was released yesterday. Is it Nov already!

Found that this error is caused by a homebridge instance on the same network as my HA instance. Turning off homebridge and rebooting the RPI running HA allows me to load ingress UI. Once I turn homebridge back on the error comes right back.
