My guess is one of your integrations are leaking sockets.

I would start by trying without any custom integration.

[supergroover]

Hi, that was one of the first things I did. Unfortunately this did not help.

I have removed all integrations, both custom and addons.

edit: When i turn discovery: on, i'm getting also this error

I have the same log issue. These messages bug me, so lets compare:

My integrations are:

• [ ] - Kodi
• [ ] - Almond
• [ ] - Adguard home
• [ ] - Google Cast
• [ ] - Mobile app
• [ ] - MQTT
• [X] - Sony Bravia
• [X] - Tado
• [X] - Roborock
• [X] - Meterologisk institutt
• [ ] - HACS

My suspicions are on the ones which aren't as common as, say, MobileApp. I've highlighted less common integrations. Are there in my list any integrations you also have @supergroover ?

Can custom automations in the HACS integrations also be a culprit? I've read you've disabled all integrations. Did you delete entities/devices as well?

edit: I run without #discovery: in my config, but with ssdp:

[supergroover]

So glad someone else has this problem 😜. I use the integrations below.

• Kodi
• Hacs
  • Xiaomi Philips Lights Integration
  • ShellyForHass (Shelly integration)
  • meteoalarmeu
  • ZiggoNext
  • Skoda Connect
  • Goodwe SEMS API to MQTT sensor
• Mqtt
• Mobile app
• Shelly
• Sony Bravia TV
• Sony PlayStation
• Xiaomi Gateway (Aqara)

I have actually already removed all integrations once. Which I then reinstalled one by one at 1 day interval. After a while this error came back, sometimes even that homeassistant did not respond at all.

[SamJongenelen]

Ok, so I've been thinking sony bravia or kodi is the issue. Do you use the bravia over wifi? I do and the integration regularly loses connection. Maybe this is the culprit?

[eloebl]

I've had this issue for months now too... Only plugins I have in common are MQTT, Google Cast and HACS.

I suspect there may be a networking issue here with one of the plugins, here's why... I've been chasing for months the Chromecasts plugin will go off into the weeds and HA can't reach them anymore (but work fine from every other network device I have) until I restart HA ( @SamJongenelen Are you also seeing this?). Also when I lose the Chromecasts, often if I try to reconnect to my MQTT server, it can't reconnect either, until I restart as well. During this time my logs fill with this SSDP error error as well.

My HA instance is loaded on a Dell SFF system using the Intel NUC Supervised image.

[SamJongenelen]

This confirms socket leak to me. What hacs integrations do you have?

[eloebl]

@SamJongenelen That's exactly what I've been suspecting as well, but not sure how to prove/debug it.

HACS integrations, (however I had this issue before any of these integrations were installed):

• Mail and Packages
• Frigate
• Elasticsearch component (publishes every 5 mins)

My HA Integrations:

• Accuweather (had issue before this plugin)
• Certificate Expiry
• ESPHome (no observed issues reaching it's devices while I am having this issue)
• Google Cast (have been having a lot of issues here with socket failures and going offline, in bug #47057)
• IMAP Mail checking for 2 sensors
• Insteon
• Internet Printing Protocol (occasional connection errors, these devices is hard wired and not wireless)
• LIFX
• Local IP Address
• Mobile App
• MQTT (Issues intermittently reaching host if I drop the connect and try to reconnect while having this issue)
• ONVIF (Occasional errors decoding streams in logs, not sure if related)
• OpenZwave (enabled but not in use)
• Rachio
• Rest call to a host every 5mins
• Roku
• Sonos
• Tuya (had issue before this plugin)
• Ubiquiti Unifi
• Zwave JS (had issue before this plugin)
• ZHA

[SamJongenelen]

In my situation, I'm using three different google cast devices over wifi, which do have unstable wifi indeed.

I'll await the update for the pycast component from your other bug

There hasn't been any activity on this issue recently. Due to the high number of incoming GitHub notifications, we have to clean some of the old issues, as many of them have already been resolved with the latest updates. Please make sure to update to the latest Home Assistant version and check if that solves the issue. Let us know if that works for you by adding a comment 👍 This issue has now been marked as stale and will be closed if no further activity occurs. Thank you for your contributions.

[SamJongenelen]

I've since moved away from Ubuntu to supported host and my errors are gone. I've used restore snapshot fwiw

The SSDP implementation was replaced since this was opened.
