Phoscon ui is not accessible via reverse proxy

As described here: After update using reverse proxy sensors page is not reachable · Issue #6862 · dresden-elektronik/deconz-rest-plugin · GitHub

Describe the bug

I am accessing home assistant via reverse proxy. Everything was working just a few days ago - all of hass pages are accessible, Deconz page is accessible. When trying to access anything from the “Devices” menu - Lights, Switches, Sensor - I always get:
The webpage at https://hostname/api/hassio_ingress/someid/pwa/devices-lights.html?_v=uuid,3,2,22&gwid=someid might be temporarily down or it may have moved permanently to a new web address.

  1. Go to deCONZ plugin in hass
  2. Click on ‘Phoscon’
  3. Click on hamburger menu: Devices->Lights
  4. Observed error

Expected behavior

Devices get shown



  • Host system: HASS OS
  • Running method: RPI
  • deCONZ version: 6.19.0
  • Device: ConBee
  • Do you use an USB extension cable: no
  • Is there any other USB or serial devices connected to the host system? If so: zwave dongle

Can you please put some effort in the post? Just linking is very inconvenient.

I did put effort into the bug ticket, but it was closed.

Yes, because it was not the correct place.

Nevertheless, it’s fine now.
