Cannot add Kodi integration

Configuration Frontend
1

Hi! With Home Assistant 2024.9.1, apparently my Kodi integrations stopped working. I deleted all of them, rebooted, tried adding again – didn’t work. Rebooted some more, could add 3 of my 4 Kodi instances.

I have Kodi running on two Windows machine which are configured pretty much the same, on one machine I could add the integration, on the other I could not. All I get is a “Failed to connect”.

I can control both Kodis via Yatse, I can access both Kodis web interface, I have set them up the same. I am confusion.

The log entry:

Traceback (most recent call last):
  File "/usr/local/lib/python3.12/site-packages/jsonrpc_async/jsonrpc.py", line 33, in send_message
    response = await self._request(data=message.serialize())

    raise asyncio.TimeoutError from None
TimeoutError

During handling of the above exception, another exception occurred:

The above exception was the direct cause of the following exception:

The above exception was the direct cause of the following exception:

  1. Make sure you have enabled the web interface of your Kodi installation. https://kodi.wiki/view/Web_interface

  2. Try (temporarily for testing) turning off the firewall on the Windows machine that won’t connect.

Thank you. Accessing the web interface works, JSON interface as well, both with firewall turned on and off. Adding the integration unfortunatelly does not, neither with or without the firewall turned on / off. Usually, I get a “enter user/password” dialog, but not for that instance, just a “Failed to connect”.

Any other thing I can try? I have two similar PCs both running Windows 10. Home Assistant can integrate Kodi from the first, but not of the second. And it used to work. Thanks!
