Denon AVR Network Receivers - config_entries.py failure

Configuration
1

Hello

Please found my configuration running on Oracle Virtual Box.

  • Méthode d'installationHome Assistant OS
  • Core2026.6.1
  • Supervisor2026.05.1
  • Operating System17.3
  • Interface utilisateur20260527.4

I get the following error with " Denon AVR Network Receivers" integration with the recent version. I read lot of topics about this error message explaining that last version solved the issue. This is not the case for me. I can connect the Audio Receiver with Telnet/23 without trouble.

Traceback (most recent call last):
  File "/usr/src/homeassistant/homeassistant/config_entries.py", line 796, in __async_setup_with_context
    result = await component.async_setup_entry(hass, self)
             ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

Thanks for your help by advance.
Best regards
Christophe

Hello

I've selected "Telnet" in the denonavr Integration interface and it seems "Telnet" connection is not used.

Please found the log file.
