Tracking down a slow websocket_api http connection

1

Since HA 2023.3+ I have been getting several disconnect messages in my log file every day.
[homeassistant.components.websocket_api.http.connection] [140616556159632] Disconnected: Did not receive auth message within 10 seconds
I connect to HA with a PC, iPhone and iPad using a NGINIX reverse proxy running on a separate Raspberry PI 4. This is in my configuration.yaml

  use_x_forwarded_for: true
  trusted_proxies:
    - 192.xxx.x.xx

websocket_api:

Questions:

  1. Is there a way to trace the long connection number to a device?
  2. I have 15 refresh tokens. Are they all still valid?

I’m having the same problem. Hitting HA via nginx is VERY slow. Its taking 13 seconds to retrieve a /local jpeg file via nginx but only .02s direct. nginx hasn’t changed. Access to grafana via nginx is still working fine.
