Denon AVR Integration stop working

[piltous]

The problem

Hello, Recently, Denon AVR Integration stopped working for me with my Marantz NR1604 when it was working for years. Now I have this message "Failed to connect, please try again, disconnecting mains power and ethernet cables and reconnecting them may help" I tried to remove the power cable for 30s and change IP but not luck. I'm running the last HA os/version under Proxmox. Thanks for your help.

Hey there @ol-iver, @starkillerog, mind taking a look at this issue as it has been labeled with an integration (denonavr) you are listed as a code owner for? Thanks!

Same issue and same environment, HA VM under Proxmox. This may have something to do with HAOS v13 as there are some other issues going on. There's nothing more I can share other than I can ping my marantz av7005 but HA won't connect to it or is intermittent at best (it does look like it works sometimes). Hundreds of log messages. Here's a sampling:

The URL listed in the debug code (XML file request) returns a 404 error in my browser. Not using telnet...never have.

After installing 13.1 it appears at first boot to have fixed the issue. I was seeing connection issues immediately and there are no messages now.

Hello, Issue fixed with 13.1 update. I should have wait this update before opening this ticket. Many thanks

[piltous]

Fixed with HAOS 13.1 update
