ESP (ESP32/ESP8266, Board/Sonoff):

All devices are affected ESPHome version (latest production, beta, dev branch)

1.19.4

Affected component:

https://esphome.io/guides/getting_started_hassio.html#dashboard-interface

Description of problem:

Problem occurs in the ESPHome Dashboard.

Problem started occuring after the recent ESPHome visual/functional redesign as shown in the linked video - https://www.youtube.com/watch?v=du38Oir_xp8

When connecting to the Dashboard via either of the provided reverse-proxy addons (NGINX Home Assistant SSL proxy or Nginx Proxy Manager) then the Logs button does not work.

When using either the Nabu Casa URL or my LAN IP then the Logs button works as expected.

Problem-relevant YAML-configuration entries:

N/A

Logs (if applicable):

N/A

Additional information and things you've tried:

I have tried connecting to the ESPHome addon multiple ways and found that only the Logs button is affected; Edit, Validate, and Install all still work as expected.

When connecting via LAN IP: all 4 buttons work Nabu Casa URL: all 4 buttons work Duck DNS through NGINX Home Assistant SSL proxy addon: Logs button fails, other 3 buttons work Duck DNS through Nginx Proxy Manager addon: Logs button fails, other 3 buttons work

While connecting through the reverse-proxy, and using the Chrome Developer Console, I found and error occurs when clicking the Logs button though I have no idea what it means:

Sorry, I didn't realize there was a separate issue queue for the Dashboard and someone had already logged this problem in there: https://github.com/esphome/dashboard/issues/35#issuecomment-872540831
