Weird Connection issues

Hi HA-specialOPs.

I use the latest HassIO(9.5) with latest HA(2023.2.2) at a VM on an dedicated unraid server (run for >1year without issues).

Some days ago my hassio started to have weird connection issues:

  • some lovelace tabs are not show content or miss some entitys
  • refresh of lovelace contents don’t work or not shown (images, maps, icons)
  • sensor data is missing
  • HACS package updating load forever


  • every URL that timedout in the log works fine with a curl request from the cli on the Hassio box
  • some of the issues are gone if I open a new Tab with HA, but reload the tab don’t work

In my home-assistant.log I have kind of these messages:

homeassistant.components.sonos.exception.SonosUpdateError: Error calling SonosMediaPlayerEntity.media_play on media_player.sonos: HTTPConnectionPool(host='10.X.X.X', port=1400): Read timed out. (read timeout=9.5)
WARNING (MainThread) [custom_components.hacs] A timeout of 60! seconds was encountered while downloading, using over 60 seconds to download a single file is not normal. This is not a problem with HACS but how your host communicates with GitHub. Retrying up to 5 times to mask/hide your host/network problems to stop the flow of issues opened about it. Tries left 0

Console in DeveloperTools shows something like this after a minute or so, but requesting the timeouted URL with curl works:

Restart hassio worked for some hours, but after 3 times of “problem->restart->problem” cycle, this seemed not a temporary issue.

I think network issues are excludet, because a curl request of every timeout url work from the same Source and open another tab shows images that are not shown in a broken tab.

Also a Problem with a plugin seems unlikely, because of the core problems of all kind of connections from HA.

  • CPU/RAM/LoadAverage are all good
  • Disk hav ~3GB free space
  • Observer page shows: (what das this mean)
  • hassio->system looks good, but 85% disk usage: (will try to resize the disk, but this should not lead to connection issues) - sorry, but only one image are allowed for new users :slightly_frowning_face:

Hope anyone can help me where I can found more information or how I can debug.

Same issue here…
